Plasma surface modification of materials and their entrapment of water contaminant: A review

Recently, rapid industrialization development has discharged a large amount of various pollutants into the aquatic environment mainly containing organic and inorganic pollutants. It is an emerging issue to eliminate these pollutants to achieve better water quality. Meanwhile, it is also imperative to investigate an environmental friendly method to modify materials with great adsorption abilities. Plasma technique has been utilized as an efficient and environmental friendly method to modify adsorbents which exhibit outstanding abilities for entrapment of water contaminants. This review gives an account of the previous researches on the various adsorbents in entrapment of water contaminants, including: (i) modifications of various functional groups onto adsorbents by using plasma technique; (ii) their applications in highly efficient entrapment of water contaminant. Additionally, this review also gives the further research trend on modificaton of specific functional groups onto adsorbent in the pollutants entrapment.
