MoS_(2)/PVDF阳离子交换膜的制备及污染物去除性能

Preparation and Pollutant Removal Performance of MoS_(2)/PVDFCation Exchange Membrane

为了在提高微生物脱盐燃料电池脱盐效率的同时去除污水中的金属离子和有机染料,对传统的PVDF阳离子交换膜进行改性,通过加入MoS_(2)提高PVDF的亲水性能和吸附性能,增加了羟基等亲水基团,当加入0.5%的MoS_(2)后脱盐效率较纯的PVDF提高了66.0%.有机染料亚甲基蓝(MB)去除率提高了47.1%,金属离子铅(Pb)去除率提高了37.7%.

In order to improve the desalination efficiency of microbial desalination fuel cell while removing metal ions and organic dyes in the wastewater,the conventional PVDF cation exchange membrane was modified to improve the hydrophilic and adsorption properties of PVDF by adding MoS_(2),and hydrophilic groups such as hydroxyl were added,and the desalination efficiency was increased by 66.0% compared with that of the pure PVDF when 0.5% of MoS_(2) was added.The removal of organic dye methylene blue(MB)was increased by 47.1%,and the removal of metal ion lead(Pb)was increased by 37.7%.
