To use copper ferrocyanide (CuFC) more efficiently in wastewater treatment, the method of isotope carrying used in 137Cs removal was investigated. A calculation model based on Freundlich isotherm was established to determine the optimum initial cesium concentration, at which the highest decontamination factor (DF) could be obtained at a certain CuFC dosage. An accurate DF prediction model was developed to describe synergistic effects of sodium and potassium. A novel index called volumetric distribution coefficient (Kvd) was proposed to evaluate adsorption performance in terms of DF and concentration factor.
