摘　　要：示波极谱 -四苯硼钠法是以示波极谱图形的突变来确定终点 ,其终点直观 ,不受溶液的颜色、沉淀、赋形剂的影响 ;可将重量分析 ,非水滴定、萃取 -光度分析变为示波滴定分析 ,具有准、快、简、省的特点 ,有广泛的应用前景。An oscillographic titrimetric method with sodium tetraphenyl boron is described for pharmaceutical and metallurgical analyses. Since the proposed method is based on the visual display of a sharp oscillographic end _ point and is not affected by the colors of the solution, precipitate and excipient, it can be employed to replace gravimetric analysis, non _ aqueous titration, and extraction-photometric analysis. The method is accurate, rapid, simple and cheap, and hence has large potential for extensive application.
