作者利用新发现的很稳定的锆-8-羟基喹啉-5-磺酸-EDTA三元荧光络合物的特殊反应及锡和镓的络合物会被EDTA分解的选择性反应,根据作者提出的金属络合物在苯基柱上的保留机理,在试验的基础上建立荧光-反相离子对高效液相色谱法连续测定锡、镓、锆的新分析方法。方法快速,准确,干扰小,适于实际样品分析。检测限分别为1.05ng,0.20ng和0.25ng,相对标准偏差在1.2％～4.4％之间。 The authors utilize the newly discovered special reaction of a very stable zirconium-8-quinolinolato-5-sulfonic acid-EDTA tris-fluorescent complex and the selective reaction of tin and gallium complexes to EDTA decomposition by the authors Based on the experimental results, a new analytical method of continuous determination of tin, gallium and zirconium by high performance liquid chromatography with fluorescence-reversed-phase ion pair was established. The method is fast, accurate and small in interference, suitable for real sample analysis. The detection limits were 1.05ng, 0.20ng and 0.25ng respectively, with relative standard deviations between 1.2% and 4.4%.
