Abstract: The use of peanut and pistachio shells as an adsorbent for the removal of Brillant Blue and K-RED 198, Metil Oranj, and Metilen Blue was investigated. The commonly used isotherm models were applied for data obtained from further batch studies. Dye removal capacity is as follows 65% for Brillant Blue, 73 % for KRED 198. Freundlich isotherm model were found to be the best fitted one and based on Friuendlch isotherm model adsorption capacities were 4,58 mg/g for Brillant Blue, and 4,33 mg/g for K-RED 198 at peanut shells, and 4,04 mg/g for Brillant Blue, and 4,64 mg/g for K-RED 198 at pistachio shells. Kinetic examinations were also carried out for two dyes tested and it was found that adsorption kinetic was best described by pseudo first-order kinetic model.
