合成了ＴＡＤＮｍ，研究了ＴＡＤＮｍ与Ｎｉ（Ⅱ）的显色反应。在ｐＨ６．６０的缓冲溶液中，０．０２０％ＳＬＳ存在下，Ｎｉ（Ⅱ）与ＴＡＤＮｍ形成１：１的红色络合物，λｍａｘ为５１０ｎｍ，ε为５．０×１０４Ｌ·ｍｏｌ－１·ｃｍ－１，稳定常数为３．８×１０１２。方法用于合金中微量镍的测定，结果满意。
TADNm was synthesized and the color reaction of TADNm with Ni (Ⅱ) was studied. In the buffer solution of pH6.60, Ni (Ⅱ) forms a 1: 1 red complex with TADNm in the presence of 0.020% SLS, λmax is 510 nm and ε is 5.0 × 104 L · mol -1 cm -1, the stability constant is 3.8 × 1012. The method was applied to the determination of trace nickel in the alloy with satisfactory results.
