Adsorption of Cr (VI) from aqueous solutions on tea wastes and coconut husk has been studied. The effect of experimental parameters like contact time, adsorbent dosage, initial metal ions concentration and pH has been investigated. The percentage removal of chromium ions increases with the increase ill contact time and dosage of adsorbent. Adsorption of Cr (VI) shows maximum adsorption capacity of 34.25 mg/g and 21.59 mg/g with tea waste and coconut husk respectively at pH 2. The removal of Cr (VI) increases with the increase in adsorbent dosage, the optimum dosage being 8 mg/L. The percentage removal of Cr in tea waste and coconut husk is found to be 86% and 82% respectively. Adsorption data have been modelled with the Freundlich and Langmuir adsorption isotherms and various first order kinetic equations. These isotherms are found to be applicable. The various kinetic models used are Natarajan-Khalaf equation, Lagergren equation, Bhattacharya and Venkobachar equation, and the Intra-particle diffusion model. An excellent fit is obtained by the Lagergren equation. Thus, adsorbents prepared from tea waste and coconut husk could be used for the removal of Cr (VI) from aqueous solutions.
