摘要
将用NaOH溶液和无水乙醇的混合液改性后的马尾藻进行固定化,测定其对废水中Pb^2+的吸附性能,实验表明:在pH值为10,固定化马尾藻和Pb^2+质量比为20%,废水温度为40℃,吸附时间为4 h时,固定化改性马尾藻基生物吸附剂吸附能力最强,吸附率达93%,该方法工艺简单,处理成本较低,不易造成二次污染。
Immobilizing the sargassum modified by the mixture of NaOH solution and absolute ethanol,the adsorption performance of sargassum on Pb^2+ in wastewater was determined.Experiments show that:When pH is 10,the mass ratio of immobilized sargassum and Pb^2+ is 20%,the wastewater temperature is 40℃ and the adsorption time is 4 h,the immobilized modified sargassum biosorbent has the strongest adsorption capacity and the adsorption rate is 93%.The method is simple,the processing cost is low and it is not easy to cause secondary pollution.
