５－Ｂｒ－ＰＡＤＡＰ分光光度同时测定铜基合金中Ｎｉ和Ｆｅ在表面活性剂ＴｅｒｇｉｔｏｌＮＰＸ存在下，Ｎｉ（Ⅱ）和５－Ｂｒ－ＰＡＤＡＰ反应生成的配合物的吸收峰分别位于５２０和５６０ｕｒｎ。Ｆｅ（Ⅱ）５－Ｂｒ－ＰＡＤＡＰ体系在同样的条件下形成的螯合物的吸收...
Simultaneous Determination of Ni and Fe in Copper-based Alloys by 5-Br-PADAP Spectrophotometry The absorption peaks of the complexes formed by the reaction of Ni (Ⅱ) and 5-Br-PADAP in the presence of the surfactant TergitolNPX are located at 520 and 560 nm, respectively. Fe (Ⅱ) 5-Br-PADAP system under the same conditions chelate absorption ...
