【摘要】 表面活性剂和多元络合物在吸收光度法中的应用,可以大大地提高测定的灵敏度,增强选择性,令人瞩目,应用很多,已有不少评述和报导[1-3]。有关锰铬天青S邻菲口罗啉溴化十六烷基三甲基铵(MnCASphenCTMAB)四元络合物的形成及其分析应用已有报导:“该绿色的四元络合物在pH=10.2...更多还原

【Abstract】 A blue quaternary complex of manganese with o phenanthroline, chromazurol S and cetyltrimenthyl ammonium bromide has been formed in the pH range of 10.2 to 11.0. The molar absorptivity is9.0×10 4L·mol -1 ·cm -1 . The wavelength of maximum absorption is 613nm abiding Beer’s law in the range of 0 24μg·25ml -1 of Mn(Ⅱ). The sensitivity and accuracy of the method is superior.更多还原
