用Ｂｒ－ＰＡＤＡＰ分光光度法同时测定铜基合金中的镍和铁Ａ、Ｃ、Ｓｐｉｎｏｌａ等在ｔｅｒｇｉｔｏｌＮＰＸ表面活化剂存在下，镍（Ⅱ）和Ｂｒ－ＰＡＤＡＰ反应形成的络合物在５６０ｍ、处有最大吸收峰。在相同条件下，Ｆｅ（Ⅱ）－ＰＡＤＡＰ体系形成的螫合物在６６０...
Simultaneous Determination of Nickel and Iron in Copper-Based Alloys by Br-PADAP Spectrophotometry A, C, Spinola et al. The complex formed by the reaction of nickel (Ⅱ) and Br-PADAP in the presence of tergitolNPX surfactant at 560m The maximum absorption peak. Under the same conditions, Fe (Ⅱ) -PADAP system formed complexes in 660 ...
