Popis:	This work focuses on the crystal violet removal from aqueous solution using raspberry leaves powder as adsorbent materials. SEM and colour analyses were used to characterize the adsorbent surface. The influence of pH, adsorbent dose and initial dye concentration was studied. Equilibrium modeling was performed to characterize the adsorption process and to determine the maximum adsorption capacity. Sips isotherm characterizes the adsorption and the maximum adsorption capacity, 264.5 (mg/g) was better compared with other similar adsorbents. The obtained results indicate that adsorbent material, obtained from raspberry leaves, is very suitable to be used for crystal violet removal from aqueous solutions.
