The equilibrium, kinetic and thermodynamics of the adsorption of chromium (VI) from aqueous solution onto Z075 and Z300 were investigated. Thermodynamic parameters and K-# equilibrium constant of activation were calculated. Langmuir, Temkin and Dubinin-Radushkevich (D-R) isotherm models were used to describe the adsorption of Cr(VI) onto ZnO powders. The monomolecular adsorption capacity of Z075 and Z300 was determined as 980 and 1050mgg(-1) for Cr(VI), respectively.eninfo:eu-repo/semantics/closedAccesschromiumadsorptionzinc oxide powdersisothermskineticsthermodynamicsArticle92349650210.1002/cjce.218362-s2.0-84895060295Q2WOS:000330606200009Q3
