研究了钨和锆水杨基荧光酮及溴化十六烷基三甲基铵在不同酸度时形成三元胶束配合物的差异．在０．１０－０．３０ｍｏ１．Ｌ－１ＨＣｌ介质中，二者形成的胶束配合物吸收曲线严重重叠，且在一定浓度范围内吸光度加合性良好；酸度为０．９６－１．２０ｍｏ１·Ｌ－１ＨＣｌ时，钨配合物吸收曲线无变化，而锆配合物在原波长处基本无吸收．依据这种酸度差异建立了连续测定钨和锆的胶束增溶分光光度法．测定范围分别为２．０－８．０（Ｚｒ）μｇ／２５ｍＬ和４．０－１２．０μｇ（Ｗ）／２５ｍＬ．用本法测定了铝合金及模拟样品中钨和锆的含量，结果满意．
The differences of ternary micellar complexes formed at different acidity between tungsten and zirconium salicylfluorone and cetyltrimethylammonium bromide were studied. At 0.10-0.30mo1. L-1HCl medium, the absorption curves of the micellar complexes formed by the two were seriously overlapped, and the absorbance of the micelles complexed in a certain concentration range was good. When the acidity was 0.96-1.20 mol · L-1HCl, the absorption of the tungsten complex There is no change in the curve, whereas the zirconium complex has essentially no absorption at the original wavelength. Based on this difference in acidity, micellar solubilization spectrophotometry for the continuous determination of tungsten and zirconium was established. The measurement ranges were 2.0-8.0 (Zr) μg / 25 mL and 4.0-12.0 μg (W) / 25 mL, respectively. The contents of tungsten and zirconium in the aluminum alloy and the simulated sample were measured by this method and the results were satisfactory.
