Abstract: In the present study fruit waste pretreated with Phosphorous (V) Oxy chloride is used for adsorption of Malachite Green (MG).Inorder to investigate the effects of pretreatment on the cationic dye adsorption, kinetics and capacities of raw fruit waste (RFW) and Phosphorous (V) Oxy Chloride treated fruit waste(TFW) to remove MG from aqueous solutions were compared. The effects of various experimental parameters (e.g., Initial pH, dye concentration, contact time) were also studied. According to the maximum adsorption capacity obtained, adsorption capability of fruit waste is significantly increased after phosphorous (V) Oxy Chloride treatment. Both adsorption isotherms of RFW and TFW fitted the Langmuir model well. The processes of uptake followed pseudo-second order rate kinetics. The results in this study indicated that treated fruit waste is a promising adsorbent for remaining MG from aqueous solution.
