Abstract
A new composite ion exchanger tamarind 5‐amino salicylic acid hydroximate [TASAH] resin was synthesized for removal of toxic metal ions, which have good ion‐exchange capacity, higher stability, reproducibility and selectivity. The characterization of the resin was carried out by determining the ion exchange capacity, elemental analysis, pH titration, FT‐IR spectra and thermal analysis (TGA). The distribution coefficients (Kd) of toxic metal ions were determined in aqueous solution and effluent of Karishma Textile at different pH. On the other hand, physical property of TASAH resin was also studied. The effects of pH, agitation speed, treatment time, flow rate, contact time, temperature and adsorbent dose, on the removal of metal ions from industrial wastewater were investigated. The adsorbed metal ions were effectively eluted by different strength of acid solution. The resin is amenable for continuous process and can be regenerated several times. The adsorption of different metal ions on TASAH resin follo...
