石墨烯复合气凝胶在水污染治理方面的应用分析

Application Analysis of Graphene Composite Aerogel in Water Pollution Control

为提升GA材料的机械性能,实现水污染的有效治理,通过将天然橡胶乳液与GA的水性分散液混合制备GA/NRL,吸附测试结果表明:对MB正电性染料吸附效果好,且对轻油、重油有机溶剂的吸收量分别是自身质量130、276倍,吸油、吸水效果好。循环吸附效果表明:对十二烷的吸油能力随循环系数的增加而保持稳定,且经4次循环后,还能够将材料中70%左右的油去除,循环利用性能好。

In order to improve the mechanical properties of GA material and achieve effective treatment of water pollution,GA/NRL was prepared by mixing natural rubber lotion and GA aqueous dispersion.The adsorption test results showed that the adsorption effect on MB positive dyes was good,and the absorption capacity of light oil and heavy oil organic solvents was 130 and 276 times of their own quality,respectively,with good oil absorption and water absorption effects.The cyclic adsorption effect shows that the oil absorption capacity of dodecane remains stable with the increase of the cyclic coefficient,and after 4 cycles,about 70% of the oil in the material can be removed,indicating good cyclic utilization performance.
