Technical field
The present invention relates to a kind of sorbing material, particularly one is using orange peel as raw material, a kind of sorbing material prepared by modification, belongs to sorbing material field.
Background technology
Along with the development of process of industrialization nearly decades, the utilization of heavy metal is more and more extensive, and incident heavy metal pollution problem is also more and more serious, and particularly the discharge of heavy metal-containing waste water gets more and more.The waste water of many industrial discharges such as plating, ore dressing and process hides, waste gas and waste residue often cause the heavy metal pollution of water environment.In waste water, various harmful material is enriched in biological chain through water body, finally enter human body, destroy normal physiological metabolism activity, the heavy metal ion wherein contained is that environmental pollution is the most serious and to one of maximum harmful substance of human health risk, heavy metal can not biodegradation, very harmful to organism, so the process of heavy metal pollutant effluents seems especially urgent.
At present, effective separating technology for removing heavy metal ions in sewage has: precipitation, ion-exchange, electrochemical treatments, membrane technology, evaporation coagulation, counter-infiltration and electrodialysis etc., but the application of these technology is sometimes by technique and economic restriction, the method that heavy metal is removed in organism absorption in recent years by living causes concern, this method mainly utilizes hyperaccumulative plant, algae and microorganism heavy metal have the heavy metal in larger adsorption capacity removal waste water, but dispose of sewage by the biomass of organism itself and the restriction of growth characteristics with the organism lived, therefore these class methods are also unsuitable for large-scale application so far.
Cellulose is natural resources that are the abundantest on the earth, that can recover, and have inexpensive, degradable and do not produce the features such as pollution to environment, therefore countries in the world are all attached great importance to cellulosic research and development.Cellulose is formed by many β-D-Glucose molecular dehydration condensation, and cellulose can produce the functional high molecule material of different purposes through a series of chemical modification reaction.Modified cellulose class adsorbent is one of important development direction of current cellulose functional high molecule material.Some pericarp membrane has multi-layer micro-fiber structure, the present invention using orange peel as cellulosic source, under the effect of isopropyl alcohol, NaOH solution and oxalic acid solution, modification is prepared into a kind of sorbing material, this sorbing material can be used for wastewater treatment, efficient and environmental protection, does not cause secondary pollution.
