摘要
讨论了新型水溶性显色剂5－Br－PADCAP与镍（Ⅱ）的最佳显色反应条件。在pH为8条件下，配合物的最大吸收波长为562nm，摩尔吸光系数达1．03X105。所建立的方法可用于铝合金中微量镍的测定。
The optimum reaction conditions of the new －type colour －producing reagent, (5 －Br－ PADCAP) with Nickel (Ⅱ) are reported. The results show that the reagent reacts with Ni(Ⅱ) to form stble a blue－violet complexat PH 8 and the molar absorptivity is 1. 03 X 105L. mol－1. cm－1 at 562nm. The reagent is suitable to spectrophotometric deterrnination of trace of Nickel in aluminium alloy.
