摘要
研究了用交流示波极谱法连续快速滴定LaNi4.5Sn0.5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,应用于该合金分量测定获得满意结果。
A Study on the oscillopolarographic titration of La,Ni and Sn in LaNi 4. 5 Sn 0. 5 Alloy is reported in this paper, The optimum conditions for the titration is established and the method proposed has the advantages of being simple,rapid and ac curate. The deep colour of the sample solution and the presence of some precipitate in the solution do not interfere the titration. The results obtained are proved to be more accurate and precise than other chemical methods.
