Synthesis, Characterization and Application of Green Chelating BE-TH Resin for the Treatment of Industrial Effluents: A Novel Approach.

Abstract

Industrial effluents containing heavy metals pose a significant threat to the environment and human health. In this study, a green chelating resin BE-TH was synthesized using barley as a natural biopolymer. The resin was developed to provide an efficient, sustainable, and cost-effective solution for heavy metal removal from industrial wastewater. The synthesis involved chemical modification of barley to enhance its chelating properties.

The resin was characterized using FT-IR, TGA-DTA, and SEM. The FT-IR analysis confirmed the successful incorporation of chelating functional groups, TGA demonstrated its thermal stability up to 300°C, and SEM revealed a porous structure conducive to effective adsorption. The % removal efficiencies of the resin were observed under various conditions with effect of pH, contact time, and resin dosage as well as their practical application to the industrial waste water was conducted.  The result showed that the BE-TH resin efficiently removed heavy metals such as Ni(II), Cu(II), and Zn(II), with over 70% removal efficiency with respect to resin dosage. The study demonstrated the potential of BE-TH resin as an innovative and eco-friendly material for industrial effluent treatment, promoting green chemistry principles and resource valorization.
