Description

[0001] background technical field

[0002] The present disclosure relates to nanocomposites, and in particular to graphene-based nanocomposites. technical background

[0003] Chemical waste generated in industrial, domestic and agricultural activities continues to pollute water. In addition to pollutants produced by human activities, natural pollutants in water sources have also brought great harm.

[0004] Various technologies have been invented to alleviate the water pollution problem. A variety of methods have been employed and developed to separate waste materials from contaminated water, including absorption, sedimentation, membrane separation, amalgamation and ion exchange. Of all these methods, absorption has proven to be more economical and efficient, especially for removal of contaminants from dilute solutions. To separate pollutants from water, a large number of absorbents have been developed. The efficacy and utility of an absorbent depends largely on the affi...
