Abstract
World water resources are barely alive due to various factors such as rise in population, adverse changes in the environment and the effects of pollutants, which increase the demand for fresh-water. Numerous techniques have been developed to solve the problem of water inadequacy, but most of them are adverse with respect to the environment and economy. Graphene-oxide (GO) nanopore materials may be an effective solution for water-purification due to its properties of easy fabrication and modification. This next-generation membrane has high waterflux, selectivity, and permeability to selected molecules. In this discussion, we have covered the latest technologies and potential applications of GO for waterpurification, which shall help researchers to get quick ideas for future research to design and fabricate multi-layered GO membranes. This article gives a snapshot of current status and proposed strategies of graphene-membranes for water treatment with earlier information to wastewater management and stimulated progress in this area from 2017 to date. The future challenges and opportunities in this field have also been highlighted.
Keywords: GO, nanocomposite membranes, wastewater effluents, fouling, water-flux, desalination, fabrication.
