A Brief Overview of the Removal of Fluoride and Chromium Using Polymer Adsorbents

Bharti ., M. Srivastava, A. Srivastava


Water tainted with heavy metals are the serious worldwide issues face today because of economic and industrial growth. Even at trace amounts, hexavalent chromium is a significant metal ion pollutant that is highly harmful to humans, animals, plants, and microbes. There are several methods for purifying water, but adsorption is one of the most straightforward, practical, and cost-effective approaches. Chromium is one such significant metal that may be released by businesses that manufacture iron, steel, lather, and electroplate. The effectiveness of various strategies for removing fluoride is also discussed in the present review. Adsorption transformation has been researched extensively and provides pleasant outcomes, especially with mineral-based or surface-modified adsorbents, in relation to a few therapeutic advancements related to fluoride removal. In this study, an overview of several adsorbents, as well as their adsorption capabilities under various conditions, has been presented. Fluoride and Cr (VI) have the potential to be both carcinogenic and mutagenic, as well as being able to represent a major hazard to living organisms, making their efficient removal before release into the environment an important concern from both a biological and an environmental standpoint. The creation of innovative polymer adsorbents and their use in areas with possible practical significance are the major topics of the paper's discussion of the issues raised. This paper's main goal is to provide a quick update in the relevant fields and, ideally, some fresh perspectives on existing and emerging practices
