In this present study, adsorption of Cr (VI) ions on tamarind tree bark adsorbent has been studied through using batch adsorption techniques. The main objectives of this study are to 1) investigate the chromium adsorption from aqueous solution by tamarind tree bark, 2) study the influence of pH, contact time, adsorbent dose, particle size and initial chromium concentration on adsorption process and 3) determine appropriate adsorption isotherm and kinetics parameters of Cr (VI) adsorption on tamarind tree bark. The various parameter’s were determined with the help of synthetic chromium sample and by using electroplating industrial wastewater sample, the parameters adsorbent dose, contact time and particle size were determined. The results show that higher Cr (VI) adsorption was observed at lower pH, and maximum Cr (VI) removal 97% obtained at pH value 1.0 with 30 minutes contact time, adsorbent dose 3.75g/l of particle size 150µ and 5mg/l initial Cr (VI) concentration. The adsorption of Cr (VI) by tamarind tree bark powder decreased at the higher initial chromium concentration. The adsorption of Cr (VI) by tamarind tree bark powder increased with increase in adsorbent dose and decrease in size of adsorbent. The obtained results showed that the adsorption of Cr (VI) by tamarind tree bark follows Freundlich isotherm. The results indicate that tamarind tree bark can be employed as a low cost alternative to commercial adsorbents in the removal of Cr (VI) from wastewater.
