摘　　要：研究了用交流示波极谱法连续、快速滴定铬铁合金分量的新方法。方法不用指示剂,有色溶液及沉淀不干扰,应用于合金分量测定获得满意结果。A study on the AC oscillopolarographic titration of Cr and Fe successively in Cr-Fe Alloy is reported in this paper. The optimum conditions for the titration are established and the proposed method has the advantage of being simple, rapid and accurate. The deep colour of the sample solution and the presence of some precipitates in the solution do not interfere the titration. The results obtained are proved to be more accurte and precise than that of some other chemical methods.
