dc.description.abstractThe pistachio shell was modified using different chemical agents and utilized as an adsorbent for the adsorption of AV 17 dye in an aqueous solution. Maximum removal of 93.04% was obtained for pistachio shell activated with 10 NH2SO4 . The physicochemical properties of activated pistachio shell were characterized by pH(pzc), FTIR, BET, and SEM-EDX analysis. The results showed that the AV 17 adsorption capacity was positively correlated to the BET surface area. The best fit of kinetic data to pseudo-second-order kinetic was determined. The adsorption follows both the Langmuir and Temkin isotherms. The Langmuir adsorption capacity was determined to be 26.455 mg/g at the initial dye concentration of 160 mg/L. The endothermic nature of adsorption was confirmed by the acquired thermodynamic data. Maximum desorption of 97.33% was achieved in 0.2 M NaOH for AAPS in the first cycle. This is very important for the economic use of the adsorbent. The findings demonstrate that activated pistachio shell may be a good alternative for color removal from industrial effluents.
