摘要 使用GB601-2002方法配制硝酸银标准溶液时,根据记录的标液滴加量V和对应的溶液电位数(mV),尝试使用小波分解处理数据,以确定滴定终点并计算待标定硝酸银标液的浓度。计算结果与使用二级微商法计算的结果作了对比,经统计检验,有95%的把握认为两种方法所得结果无显著差异。 In preparing the silver nitrite standard solution by method GB601-2002, the wavelet transformation was attempted to be used in determining the end-point and consumption the concentration of silver nitrite standard solution by the consumption volume the increment volumn V of standard solution and the electric potential value of solution. The opposite experiment on method of wavelet transformation and method of second - time derivative were carried on, and there are no significant differences between two method.
