Abstract
Description
Изобретение относится к способам группового извлечения элементов (Mn, Fe, Zn, Cu, Pb) из природных и сточных вод для последующего их аналитического определения. The invention relates to methods for group extraction of elements (Mn, Fe, Zn, Cu, Pb) from natural and waste waters for their subsequent analytical determination.
Целью является увеличение избирательности и степени извлечения. Поставленная цель достигается способом извлечения предложенных микроэлементов из растворов путем введения полимерного хелатного сорбента полистирол - азо- салициловой кислоты, сорбцию проводят при рН 5,3-6,0 и при температуре 15-30оС.The goal is to increase selectivity and recovery. This goal is achieved by the method of extraction of the proposed trace elements from solutions by introducing a polymeric chelating sorbent polystyrene - azosalicylic acid, sorption is carried out at pH 5.3-6.0 and at a temperature of 15-30 about C.
Хелатный сорбент полистирол - азо-салициловая кислота H
Сорбционная емкость сорбента по извлекаемым металлам составляет 21,7 мг ΣMn, Fe, Zn. Cu. Pb/Г сорбента. The sorption capacity of the sorbent for recoverable metals is 21.7 mg ΣMn, Fe, Zn. Cu. Pb / g sorbent.
Зависимость степени сорбции от рН среды представлена в табл. 1. Количественная сорбция (R= 95-100% ) наблюдается в следующих значений рН: для марганца 5,3-10,0; для цинка 5,0-8,0; для железа 3,7-10,0; меди 4,5-7,5; свинца 4,7-6,0. The dependence of the degree of sorption on the pH of the medium is presented in table. 1. Quantitative sorption (R = 95-100%) is observed in the following pH values: for manganese 5.3-10.0; for zinc, 5.0-8.0; for iron, 3.7-10.0; copper 4.5-7.5; lead 4.7-6.0.
Совместное количественное извлечение Mn, Fe, Zn, Cu, Pb происходит в интервале значений рН 5,3-6,0. Joint quantitative extraction of Mn, Fe, Zn, Cu, Pb occurs in the range of pH 5.3-6.0.
В табл. 2 представлены сравнительные результаты по избирательности групповой сорбции Mn, Fe, Zn, Cu, Pb предлагаемым сорбентом и известным наиболее широко используемым полистирол-азо-4-окси-3-арсонобензолом. Из таблицы следует, что избирательность групповой сорбции указанных элементов предлагаемым сорбентом выше избирательности на несколько порядков, чем известные сорбенты. Предлагаемый способ позволяет количественно извлекать Mn, Fe, Zn, Cu, Pb из природных и сточных вод в присутствии n˙102-n˙106 - кратных избыточных количеств Ca, Mg, K, Na, Ba, Sr, Li, AI, Ti.In the table. 2 presents comparative results on the selectivity of group sorption of Mn, Fe, Zn, Cu, Pb by the proposed sorbent and the most widely known polystyrene-azo-4-hydroxy-3-arsenobenzene. From the table it follows that the selectivity of the group sorption of these elements by the proposed sorbent is higher by several orders of magnitude than the known sorbents. The proposed method allows to quantitatively extract Mn, Fe, Zn, Cu, Pb from natural and wastewater in the presence of n 210 2 -n 610 6 - multiple excess amounts of Ca, Mg, K, Na, Ba, Sr, Li, AI, Ti.
В табл. 3 представлены данные по результатам сорбции от продолжительности перемешивания, а в табл. 4 - от температуры процесса. In the table. 3 presents data on the results of sorption on the duration of mixing, and in table. 4 - from the process temperature.
Сущность способа заключается в том, что в анализируемую воду, после создания соответствующей среды с рН 5,3-6,0, добавляют 50 мг сорбента, смесь перемешивают не менее 60 мин при температуре 15-30оС и фильтруют раствор через фильтр "белая лента", концентрат промывают водой и десорбируют элементы 1М HCl. В элюатах определение элементов выполняют методом атомно-абсорбционной спектроскопии или любым другим методом.The method consists in that the water to be analyzed after the creation of the appropriate medium at
Пример. Определение марганца, железа, цинка, меди и свинца в природных и сточных водах. Example. Determination of manganese, iron, zinc, copper and lead in natural and waste waters.
К 500 мл анализируемой воды, доведенной 2 М HCl до рН 5,3-6,0 прибавляют 50 мг сорбента полистирол-азо-салициловую кислоту. Раствору перемешивают на магнитной мешалке в течение не менее 60 мин при температуре 15-30оС. Сорбент отфильтровывают через фильтр "белая лента". Концентрат промывают 3-4 раза дистиллированной водой и десорбируют Mn, Fe, Zn, Cu, Pb 1M HCl. Элюат собирают в мерную пробирку емкостью 10 мл. В полученном растворе элементы определяют методом атомно-абсорбционной спектроскопии, работу выполняли с трехщелевой горелкой в пламени ацетилен-воздух. Источниками резонансного излучения были лампы полого катода.To 500 ml of analyzed water, adjusted with 2 M HCl to pH 5.3-6.0, 50 mg of the sorbent polystyrene-azo-salicylic acid are added. The solution was stirred on a magnetic stirrer for at least 60 minutes at a temperature of 15-30 ° C is filtered through a sorbent filter "white ribbon". The concentrate is washed 3-4 times with distilled water and stripped with Mn, Fe, Zn, Cu, Pb 1M HCl. The eluate is collected in a 10 ml volumetric tube. In the resulting solution, the elements are determined by atomic absorption spectroscopy; work was carried out with a three-gap burner in an acetylene-air flame. Sources of resonant radiation were hollow cathode tubes.
