Iron content must be determined accurately in the process of preparing manganese zinc ferrite from waste dry batteries. A method is used to determine iron content by titration of potassium dichromate with aluminum powder as reducing agent. Meanwhile, the effects of manganese and zinc elements on the results of determination are studied. The results show that this method is simple, rapid and accurate. The iron recovery is in the range of 97.0%~99.6%.
