Cr (VI) Remediation with Economical Adsorbents: A Path to Environmental Sustainability

Authors- Shilpa S.Patil, Dr.S.V.Anekar

Abstract-Hexavalent chromium Cr(VI) is a highly toxic heavy metal frequently found in Electroplating,Tanneries,Textile & paint industrial wastewater. This study explores the use of waste foundry sand (WFS), Bael fruit shell (BFS), and copper benzene-1,3,5-tricarboxylate (Cu-BTC) metal-organic frameworks (MOFs) for Cr(VI) adsorption. Batch adsorption experiments were conducted under varying pH, Cr(VI) concentrations, contact time, and adsorbent dosages. Characterization of the adsorbents was performed using SEM analysis. The results showed that the Cu-BTC MOF had the highest adsorption capacity, with significant synergies observed when combined with WFS and BFS. These findings indicate that integrating waste materials with MOFs can provide a cost-effective and efficient method for environmental remediation.
