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. In this present study the parameter like pH, contact time, adsorbent dose and initial chromium concentration were determined with the help of synthetic chromium sample. Also with the help of electroplating industrial wastewater sample, the parameters adsorbent dose, contact time and particle size were determined.The results of this study 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...
