In this study, unexpended perlite waste obtained from a factory producing expanded perlite was used as adsorbent. Malachite green (MY), which is a cationic dyestuff, was used as adsorbed material. The pore properties including the BET surface area, pore volume and average pore diameter were characterized. The chemical composition of the perlite was analysed by XRF. The effects of initial pH, the amount of adsorbent, contact time and initial dyestuff concentration were examined. The adsorption kinetics of dyestuff obeys the pseudo second-order kinetic model. The experimental data indicated that the adsorption isotherms are well described by the Langmuir isotherm equation. 99% dyestuff removal was obtained under optimum conditions. As a result, it was found that perlite waste was a suitable adsorbent for malachite green dyestuff.
