Description
개시된 내용은 세슘제거용 맴브레인 필터의 제조방법에 관한 것으로, 더욱 상세하게는 우수한 세슘제거 성능을 나타낼 뿐만 아니라, 기타 유해물질 및 세균 제거에 탁월한 효과를 나타내는 세슘제거용 맴브레인 필터의 제조방법에 관한 것이다.
The present invention relates to a process for producing a cesium-removing membrane filter, and more particularly to a process for producing a cesium-removing membrane filter which not only exhibits excellent cesium removal performance but also exhibits an excellent effect for removing other harmful substances and bacteria .
각 가정에 공급되는 수돗물은 엄격하게 관리되는 정수장에서 정수처리 단계를 거쳐 깨끗하게 정수된 물이지만, 정수장에서 정수된 물이 수도배관을 통해 공급되는 과정에서 물이 오염되는 문제가 발생한다. 즉 수도배관은 부식성이 강한 금속재로 이루어지며 오랜 기간 사용하더라도 새로운 배관으로 교체하는 것이 어렵기 때문에 노후한 수도배관으로 인해 오염된 수돗물이 공급된다.The tap water supplied to each household is cleanly purified water from a strictly controlled water treatment plant, but there is a problem that water is contaminated in the process of supplying purified water from a water treatment plant through a water pipe. That is, the water pipe is made of a corrosive metallic material, and it is difficult to replace it with a new pipe even if it is used for a long period of time. Therefore, contaminated tap water is supplied by the old water pipe.
따라서, 가정용 정수기, 비데 등의 정수장치에는 적어도 하나 이상의 전처리필터가 장착된다. 전처리필터에는 전처리 침전필터와 프리카본 필터 등이 있는데, 전처리 침전필터(Sediment pre-filter)는 녹이나 흙, 모래, 먼지를 비롯한 각종 찌꺼기 등 불순물을 제거함으로써 초기 단계서부터 정수효과를 극대화하는 기능을 수행하고, 프리카본 필터(Pre-carbon filter)는 수돗물의 소독용으로 첨가된 염소성분 및 그로 인하여 생성될 수 있는 THM(트리할로메탄) 등의 유기화학물질과 냄새를 제거하는 기능을 한다.Therefore, at least one pretreatment filter is installed in a water purification apparatus such as a household water purifier or a bidet. Pretreatment filters include pretreatment sedimentation filters and free carbon filters. Sediment pre-filters remove impurities such as rust, soil, sand, dust and other impurities to maximize the effect of water purification from the initial stage. , And the pre-carbon filter functions to remove odor and organic chemicals such as THM (trihalomethane) which may be generated by chlorine components added for disinfection of tap water.
이와 같은 전처리필터는 각 기능에 따른 필터가 직렬연결되는 형태로 사용되거나, 필요에 따라서는 여러 기능을 동시에 수행할 수 있는 복합필터의 형태로 제작되어 사용되기도 한다.Such a preprocessing filter may be used in the form of a series connection of filters according to respective functions, or may be used in the form of a composite filter capable of performing various functions simultaneously, if necessary.
전처리필터에는 녹이나 흙, 모래, 먼지 등의 불순물을 제거하는 기능 이외에 살균기능을 수행하기 위해, 수돗물에 함유된 세균류를 살균하고 바이러스를 비활성화시키는 요오드수지(Iodinated resin)가 포함되기도 한다.In addition to removing impurities such as rust, soil, sand and dust, the pretreatment filter also includes iodinated resin, which sterilizes the bacteria contained in tap water and deactivates the virus in order to perform a sterilizing function.
요오드수지는 강한 음이온 교환 수지와 요오드화이온이 착물화되어 이루어진 것으로, 물에 대한 용해도가 매우 낮으며 안정한 화합물을 이루고 있는 살균력이 우수한 수지이며, 지속적인 살균력과 설치의 편리성과, 경제성 등의 장점을 가지고 있다.Iodine resin is made by complexion of strong anion exchange resin and iodide ion. It has very low solubility in water and has excellent sterilizing power which is a stable compound. It has advantages such as continuous sterilizing power, easy installation and economical efficiency have.
그러나, 요오드수지는 통과한 물에 유해잔류물질을 남기지 않으며, 물의 공급과 동시에 살균 작용이 일어나므로 언제라도 안전하고 깨끗한 물을 마실 수 있도록 하는 장점이 있으나, 세슘과 같은 성분을 걸러내는 효과는 미흡한 문제점이 있었다.
However, since iodine resin does not leave any harmful residues in the passing water and sterilizing action occurs simultaneously with the supply of water, it is advantageous to drink safe and clean water at any time, but the effect of filtering out components such as cesium is insufficient There was a problem.

The binder imparts an adhesive property to the cesium adsorbent, and the cesium adsorbent is coated on the surface of the membrane through the membrane immersion step.
또한, 상기 프러시안 블루는 1 내지 50 중량부가 함유되며, 상기 세슘흡착제에 세슘흡착 성능을 부여하는 역할을 하는데, 상기 프러시안 블루는 물에 대한 용해성에 따라서 두 종류로 구분되며, 일반적으로 프러시안 블루는 Fe3 +와 [FeⅡ(CN)6] 4- 또는 Fe2 +와 [FeⅢ(CN)6] 3-의 결합으로 형성된다.The prussian blue is contained in an amount of 1 to 50 parts by weight, and plays a role of imparting cesium adsorption performance to the cesium adsorbent. The prussian blue is classified into two types according to the solubility in water, Blue is formed by the combination of Fe 3 + and [Fe II (CN) 6 ] 4- or Fe 2 + and [Fe III (CN) 6 ] 3- .
통상적으로 불용해성 프러시안 블루는 FeⅢ 4[FeⅡ(CN)6]3로 구성되며 용해성 프러시안 블루는 KFeⅢ[FeⅡ(CN)6]로 표현되는데, 상기와 같은 두 타입의 프러시안 블루의 결합과정을 아래 반응식 1 내지 2에 나타내었다.Typically, insoluble Prussian blue is composed of Fe III 4 [Fe II (CN) 6 ] 3 , and soluble Prussian blue is represented by KFe III [Fe II (CN) 6 ] The coupling procedure of blue is shown in the following Schemes 1 and 2.
<반응식 1><Reaction Scheme 1>
4Fe3 + + 3[FeⅡ(CN)6]4- → Fe4 Ⅲ[FeⅡ(CN)6]3 4Fe 3 + + 3 [Fe II (CN) 6 ] 4- → Fe 4 III [Fe II (CN) 6 ] 3
<반응식 2><Reaction Scheme 2>
K+ + Fe3 + + [FeⅡ(CN)6]4- → KFeⅢ[FeⅡ(CN)6]K + + Fe 3 + + [Fe II (CN) 6] 4- → KFe III [Fe II (CN) 6 ]
프러시안 블루에 대한 알칼리 금속 이온과의 흡착 성능은 알칼리 금속 이온의 수화상태의 크기와 관련이 있다. 따라서, 알칼리 금속 이온의 흡착능력은 Cs+≫K+≥Na+으로 차이가 생기게 된다. 이는 알칼리 금속 이온 중 프러시안 블루의 격자 구조 크기에 잘 맞는 이온 반경을 갖는 이온과 흡착력이 크게 나타나기 때문인데, 알칼리 금속의 이온반경 크기는 Cs+ (1.19)<K+ (1.25)<Na+ (1.84 A)이며, Cs+의 이온 반경이 가장 작고 프러시안 블루의 격자 구조에 잘 맞아 흡착력이 높기 때문에, 프러시안 블루로 이루어진 세슘흡착제는 세슘을 선택적으로 흡착하는 역할을 한다.The adsorption performance of Prussian blue with alkali metal ions is related to the size of the hydration state of alkali metal ions. Therefore, the adsorption capacity of the alkali metal ion is different by Cs + »K +? Na +. (1.19) <K + (1.25) <Na + (1.84 A), and the ionic radius of the alkali metal is larger than that of the ionic radius of the Prussian blue. , And since the ion radius of Cs + is the smallest and is well suited to the prussian blue lattice structure, the cesium adsorbent of Prussian blue selectively adsorbs cesium.
또한, 프러시안 블루 격자 구조 내부는 물 분자가 배위 결합하여 채워져 있어 친수성 특성을 띄고 있다. 수화된 세슘 이온은 프러시안 블루 내부의 친수성 공간에 흡착되기 쉽고, 또한 세슘 이온이 프러시안 블루 내부 공간에 트랩이 되면 FeIII 이온의 배위결합 되어 있는 물 분자의 양성자 교환에 의해 세슘이 제거되는데, 이러한 과정을 아래 반응식 3에 나타내었다.Inside the Prussian blue lattice structure, water molecules are coordinated and filled, and thus have hydrophilic characteristics. Hydrated cesium ions are easily adsorbed in the hydrophilic space inside the Prussian blue, and when cesium ions are trapped in the Prussian blue interior space, cesium is removed by proton exchange of the coordinated water molecules of FeIII ions. The process is shown in Scheme 3 below.
<반응식 3><Reaction Scheme 3>
FeⅢ-OH2+Cs+A- → {FeⅢ-OH}-Cs++H+A- Fe III -OH 2 + Cs + A - - {Fe III -OH} - Cs + + H + A -
위에 반응식 3에 나타낸 것처럼, 양성자 교환 방법으로 Cs+ 이온을 효과적으로 프러시안 블루 내부의 격자 구조에 흡착시킬 수 있게 된다.As shown in Reaction Scheme 3 above, Cs + ions can be effectively adsorbed to the lattice structure inside Prussian blue by the proton exchange method.
또한, 위에 반응식 1로 나타낸 불용해성 프러시안 블루가 회수 공정을 통해 쉽게 회수할 수 있기 때문에 세슘흡착제로 더 적합하다.In addition, insoluble Prussian blue, as shown in Scheme 1 above, is more suitable as a cesium adsorbent because it can be easily recovered through the recovery process.
상기 프러시안 블루의 함량이 1 중량부 미만이면 상기의 효과가 미미하며, 상기 프러시안 블루의 함량이 50 중량부를 초과하게 되면 상대적으로 바인더의 함량이 줄어들어 세슘흡착제의 점착성능이 저하된다.
If the content of Prussian blue is less than 1 part by weight, the above-mentioned effect is insignificant. If the content of Prussian blue exceeds 50 parts by weight, the content of the binder is decreased and the adhesion of the cesium adsorbent is deteriorated.
상기 맴브레인침지단계(S103)는 상기 세슘흡착제제조단계(S101)를 통해 제조된 세슘흡착제에 맴브레인을 침지하는 단계로, 상기 세슘흡착제제조단계(S101)를 통해 제조된 세슘흡착제에 맴브레인을 30분 내지 24시간 동안 침지하여 이루어진다.The membrane immersion step (S103) is a step of immersing the membrane in the cesium adsorbent manufactured through the step (S101) of preparing the cesium adsorbent, wherein the membrane is immersed in the cesium adsorbent prepared in the step (S101) Followed by immersion for 24 hours.
상기의 시간 동안 세슘흡착제에 침지된 맴브레인은 표면에 세슘흡착제가 고르게 코팅되어 우수한 세슘 제거성능을 나타내게 된다.The membrane immersed in the cesium adsorbent during the above-mentioned period of time exhibits excellent cesium removal performance because the surface of the cesium adsorbent is uniformly coated.
이때, 상기 맴브레인은 폴리이민, 알루미나파이버, 아마이드, 폴리프로필렌, 폴리스티렌, 폴리에틸렌테레프탈레이트 및 폴리에틸렌설폰으로 이루어진 그룹에서 선택된 하나 이상으로 이루어지는 것이 바람직하다.

The membrane coated with the cesium adsorbent through the membrane immersion step (S103) For 1 to 48 hours.
상기 건조온도가 40℃ 미만이거나 건조시간이 1시간 미만이면 건조공정의 효율성이 저하되거나 건조가 제대로 진행되지 않고, 상기 건조온도가 100℃를 초과하거나 건조시간이 48시간을 초과하게 되면 제조공정의 비용이 상승하며, 효율성이 저하된다.
If the drying temperature is less than 40 ° C or the drying time is less than 1 hour, the efficiency of the drying process is lowered or the drying is not progressed properly. If the drying temperature exceeds 100 ° C or the drying time exceeds 48 hours, The cost is increased, and the efficiency is lowered.
