研究了胡椒基荧光酮 (PIF)与铟的显色反应条件 ,体系λmax为 550nm ,ε1.15× 10 5L·mol- 1·cm- 1。铟的含量在 0～ 14μg/2 5mL内符合比尔定律 ,方法用于锡箔中铟的测定 ,结果满意
The conditions for the color reaction of piperonylfluorone (PIF) with indium were investigated. The λmax of the system was 550 nm and ε1.15 × 10 5 L · mol-1 · cm-1. The content of indium in 0 ~ 14μg / 2 5mL accord with Bill’s law, the method for the determination of indium tin foil, the results were satisfactory
