COMPREHENSIVE STUDY OF CHROMIUM HEAVY METAL ADSORPTION FROM TEXTILE WASTEWATER USING NATURAL COMPOSITE ADSORBENT

Abstract

In this work, the utilization of natural composite adsorbent for the adsorption of chromium heavy metal in textile effluent has been investigated. This research aims to study the chemical and physical characteristics of natural composite Andisol-Zeolite-Fly Ash-Activated Carbon (AZFC) on the potential adsorption of chromium ions. This study performed the characterization analysis through Fourier Transform Infrared (FTIR), X-Ray Diffraction (XRD), Surface Area Analyzer (SAA), Atomic Absorption Spectrometry (AAS), and Ultraviolet-Visible Spectrometry (UV-Vis). The optimum composition of AZFC was obtained in the andisol/zeolite/activated carbon/fly ash soil ratio is 40/40/10/10, respectively. After the adsorbent was activated, the natural composite with the various ratios have been tested with the initial standard solution of 50 ppm chromium, and the adsorption process showed 99% chromium removal ion is achievable. Further, while using the actual industrial textile wastewater containing 0.15 ppm chromium, the concentration of chromium decreased by more than 82%.
