This research work focuses on the utilization of tea bag waste of some commercial teas as a precursor for the production of an adsorbent for the removal of chromium ions from tannery waste effluent. The tea bag waste was chemically activated with 1.0 M sulfuric acid to produce the adsorbent. Nearly 100% removal of chromiumfrom real tannery waste water is achieved with the activated tea bag waste adsorbents.
