摘要
本文研究了铝(Ⅲ)-氯磺酚S络合物在乙酸-乙酸钠缓冲溶液(pH5.0)中的电化学行为,探讨了有关机理,提出了痕量铝的测定方法。线性范围5～500ng/ml,检出限3.0ng/ml。用于铜合金中铝的直接测定,结果满意。
The electrochemical behaviour of Al(Ⅲ) - sulfochlorophenol S complex was investigated in HAc - NaAc buffer solution (pH 6. 0). The mechanism of related reactions was discussed. A new simple and sensitive oscillopolarographic method was established for the determination of trace aluminium. The detection limit was 3.0ng/ml. The result for the direct determination of trace Al(Ⅲ) in copper alloys was very satisfactory.
