利用牡蛎壳制备水处理剂的应用研究

Application Studies on Oyster Shells to Make Water Treatmentre Agents

以牡蛎壳为原料制备一种新型牡蛎壳负载壳聚糖水处理剂,研究了水处理剂对水中苯酚的吸附性能。通过单因素试验确定水处理剂去除苯酚的条件,试验分析得出水处理剂去除苯酚最佳工艺条件:壳聚糖/牡蛎壳质量比0.08、pH=3、水处理剂用量0.5g和吸附时间150min。该研究对牡蛎壳为基的水处理剂的开发与利用提供科学依据。

The new water treatmentre agent of chitosan-coated oyster shells was prepared by using oyster-shell as raw materials, adsorption characteristic of phenol on water treatmentre agent was studied. Based on water treatment on the removal of phenol as the research object,using single factor experiment to mass ratio of chitosan and oyster, pH, dose of water treatment and adsorption time, ultimately determine the best extraction conditions. Through the test analysis found that water treatment on the removal of phenol optimum extraction conditions, Mass ratio of chitosan and oyster is 0.08, pH is3, dose of water treatment is 0.5g and adsorption time is 150min. Provides scientific basis for the further research and development of synthesis on oyster shells to make water treatmentre agents.
