Recent advances in remediation of synthetic dyes from wastewaters using sustainable and low-cost adsorbents

Abstract Textiles dyes effluents are most dischargeable, dangerous, and mostly concern class of pollutants in current environmental issues that can be easily identified by the human eye. Discharge of textiles effluents into water must be avoided using various treatment technologies; however, it is difficult with various techniques due to stable and complex structure of dyes. Among several techniques, adsorption gets most prominent place in water treatment technology, particularly in dyes removal. The large demand for low-cost and sustainable treatment methods has given rise to bioadsorbents. This chapter highlights the low-cost and sustainable treatment methods comprising activated carbon, zeolites, clay materials, siliceous materials, natural, industrial as well as agriculture waste and their application for dyes removal. In particular, this chapter focused on the latest status, features, and future prospects of bioadsorbents derived from natural plants materials. The advances in bioadsorbent due to chemical treatment have also been included.
