Abstract

Water pollution is a global concern, and it has affected the lives of millions of people. The delivery of  a good approach to eliminate the chemical contaminants is an emerging issue and requires continuous exploration.  Recently, extensive studies have reported interesting findings on the development of suitable methods for the  removal of chemical contaminants. In this review, the origin of different types of chemical contaminants and  their effect on the environment and human health were presented. We also reviewed the current state-of-the-art  of available and newly established techniques for the removal of the chemical contaminants. Lastly, challenges  and future directions related to this area were also tackled. This review can be positively beneficial to human,  the environment, economics and society.
