Green Approaches to Prepare Polymeric Composites for Wastewater Treatment

TL;DR: In this paper, the authors discuss on the development of various polymeric green composites with a special emphasis on chitosan, a polycationic biopolymer for the treatment of wastewater because of its excellent chelating and coagulating abilities to bind various metal ions/dyes contained in wastewater.

Abstract: Water is an indispensable link between living things and the environment but the permanently disconnection of the link will ruin the whole kingdom. Therefore, it is our responsibility to diligently take care of this essential element for sustaining our life. Here, it can be recalled that there are 97% salty water, 2% ice-capped water, and 1% freshwater of the total water on earth. As only this freshwater is being utilized to meet the needs for various purposes in different sectors in the world, so one day over time we must have to face the problem of water scarcity throughout the world, if at once we do not focus on recycling of water, particularly for industrial water. However, recycling of the industrial water is being carried out through chemical treatment of wastewater. But due to the involvement of various chemical processes, these are, on the other hand, responsible for causing environmental pollution, further, leading to climate change. Nowadays, developing green composites through green approaches is an emerging area in polymer science. The green composites are eco-friendly, efficient, reliable, and alternative to traditional composites for environmental sustainability. In this chapter, we shall discuss on the development of various polymeric green composites with a special emphasis on chitosan, a polycationic biopolymer for the treatment of wastewater because of its excellent chelating and coagulating abilities to bind various metal ions/dyes contained in wastewater.
