Abstract

Arsenic (As) contamination of soil and water bodies due to various natural and anthropogenic activities has become a primary environmental concern worldwide. The As level is increasing due to contaminated irrigation water and the use of As-based agrochemicals, which is leading to the deterioration of soil fertility. In developing countries, As concentration in drinking water has far exceeded the permissible limit stated by the World Health Organization (WHO). It is highly toxic to plants, animals, and humans with severe consequences to present and coming generations. As is a nondegradable element, and thus removed from the contaminated site, or water bodies are the only solution. Ion exchange and membrane technologies are one of the aesthetical approaches for the removal of As from wastewater. Various environmental factors such as temperature, pH, and state of reduction/oxidation influence the rate and type of ionic conversion reactions. This book chapter provides an insight into the different membrane and ion exchange technologies to assess the status of As removal from different water bodies. Attempts have also been made to summarize the role of different types of membrane technologies like microfiltration, nanofiltration, reverse osmosis, and ultrafiltration processes in As removal. Furthermore, this chapter will also compile the flaws of both the technologies and challenges which need to be investigated for developing sustainable approaches. © 2023 John Wiley & Sons, Inc.
