报道了苯重氮氨基苯对偶氮苯及其四种衍生物的合成与纯化方法,以及这些试剂与Cd~(2+)、Ni~(2+)在OP-10存在下的显色反应。实验表明,苯重氮氨基苯对偶氮苯与镍有灵敏的反应,其摩尔吸光系数可达2.0×10~5升·摩尔~(-1)·厘米~(-1)。
A method for the synthesis and purification of p - azobenzene and its derivatives was reported, and the color reaction of these reagents with Cd ~ (2 +) and Ni ~ (2+) in the presence of OP-10 was reported. Experiments show that benzene diazoaminobenzene azobenzene and nickel have a sensitive reaction, the molar absorption coefficient up to 2.0 × 10-5 mol · cm -1.
