Abstract
The effects of amendments such as lime bassanite sodium phosphate steel slag and charcoal and their compounds on the immobilization of cadmium Cd are investigated The lime–bassanite–charcoal compound shows the best remediation performance compared to other agents in conducted experiments The optimum condition for lime–bassanite–charcoal application in contaminated soil is lime–bassanite–charcoal with a mass ratio of 11/32/3 a dose of 2 of the soil weight and a liquidtosolid ratio of 35–40 additionally the agents should be added before water addition The highest Cd removal rate was 5894 ±119 with a ∆pH of 023 which is much higher than the rates reported in previous studies The compound amendment was used in a field experiment demonstrating a Cd removal efficiency of 4878 ±423 further confirming its effectiveness
