以钨、铜的PV-CTMAB为体系,在pH=5.5时,用多波长数据线性回归法同时测定微量的钨和钼。选择的波长区间为650~690nm,当钨和钼含量比率在1:3和6:1范围内,相对误差小于±8%.
Using tungsten and copper PV-CTMAB as the system, simultaneous determination of trace amounts of tungsten and molybdenum by multi-wavelength data linear regression at pH = 5.5. The selected wavelength range is 650-690 nm. The relative error is less than ± 8% when the ratio of tungsten to molybdenum is in the range of 1: 3 and 6: 1.
