摘要
Abstract
Adsorption of Cr (Ⅲ) from wastewater using cation exchange resin D001 was reseached.The thermodynamics and kinetics of adsorption process were investigated.The results show that the Redlich Peterson model can use to describe the adsorption process.The thermodynamics parameters indicate that the adsorption process is spontaneous, endothermic and adding entropy.The adsorption rate follows the pseudo-second-order kinetics model with the activation energy of 27.45kJ/mol.The kinetics experiment results show the intraparticle diffusion is the adsorption process rate-limiting step.关键词
