Biomass derived carbon blended ion-exchange resins for the removal of toxic metal ions from waste water

Abstract

Heavy metal pollution has recently emerged as one of the major environmental problems. The removal of metal ions from the environment is of serious concern due to their persistence existence. Enhancing coke is a cost-effective beneficial method for removing metal contaminants from water. In this paper, we describe the production of sulphonate-enhance coke from Indigofera tinctoria carbon incorporated with synthetic phenolic resin for the removal of metal ions from wastewater. They act as a cation exchange resin followed by column chromatography. The preparation of Indigofera tinctoria carbon has been optimized in this study. It was tested for the removal of different metals in water after it was prepared with different concentrations of H2SO4 (from 10 % to 50 %) sorbent. Fourier transform infrared spectroscopy (FT-IR) and scanning electron microscopy (SEM) were used to examine the samples. Thermogravimetric analysis (TGA) and differential thermometric analysis (DTA) were used to examine the thermal stability of the samples. The enhance coke-based work in resin- is useful as an electrode material for effectively removing heavy metals from contaminated water via the cation deionization (CDI) process. Coke is regarded as a low-cost adsorbent material for the removal of basic dyes and metal ions from polluted solutions. It has excellent thermal stability and swelling behavior for long-term applications.
