摘要：
This work describes the use of tamarindus shell as an alternative adsorbent for the removal of methylene blue and chromium(VI) species from aqueous solutions. The adsorbent at unmodified form was used in sorption studies. The solid was characterized by MEV, BET and BJH. Acidic functional groups on the surface of the adsorbent were seen by FTIR, Boehm's titration and pH,. The results showed that the kinetic equilibrium was reached after 120 and 180 min for the dye and the metal respectively. The kinetic data were better fitted to pseudo-first order for dye adsorption and to pseudo-second order for metal adsorption. The change points in sorption stages (rapid and slow phase) were defined by the MCVP parameter using Hung's algorithm. The effects of pH and ionic strength on adsorption capacity were also studied.
