The Adsorption Kinetics of Cr (Vi) Metal by Using Granulated Particles of Tamarindus Indica Seed

The objective of this study was to investigate the possibility of using granulated particle of Tamarindus Indica seed as an alternative adsorbent for the removal of Chromium (VI) ions from aqueous solutions. The effect of pH, solution temperature, contact time, initial metal ion concentration and adsorbent dose on the adsorption of Chromium (VI) by granulated particle of Tamarindus Indica seed was investigated using batch methods. Adsorption for Chromium (VI) was found to be highly pH dependent compared to the other parameters investigated. Obtained results gave an adsorption capacity of 77.56 % for Chromium (VI) at pH 2, exposure time of 3hr at 25 ºC. The data obtained from the batch processes have used to fit in Freundlich and Langmuir isotherm equations. The results suggest that granulated particle of Tamarindus Indica seed could be used as effective adsorbents for the removal of Cr (VI) ions
