The most optimum reaction conditions were explored: pH=9.0, temperature=70℃, stirring time=40min, stirring speed=120 rpm. Leaching toxicity of heavy metals from Ni-Cr ferrite prepared in the experiment was much lower than the regulated limit of Toxicity Characteristic Leaching Procedure (TCLP), indicating that Ni-Cr ferrite had a better chemical stability. 收起<<
