表面活性剂可以显著提高许多金属离子与某些酸性染料反应的灵敏度。其中长链季铵盐阳离子表面活性剂应用最多。最近报导,有非离子表面活性剂存在时,金属离子 Al、Fe、Cu、Se、Be、In、Ga 与铬天菁S反应的灵敏度特别高,并有很好的颜色反应对比度。近几年来,日本学者连续发表十多篇有关某些金属离子与一些显色剂反应时应用辛基酚聚氧乙烯醚,Triton(曲通)X-100的文章;国内,以 PAN 测定锌对应用了 Triton X-100C_8H_(17)(?)
Surfactants can dramatically increase the sensitivity of many metal ions to certain acidic dyes. One of the most widely used long-chain quaternary ammonium cationic surfactants. It has recently been reported that the sensitivity of the metal ions Al, Fe, Cu, Se, Be, In, Ga to the reaction with chromocyanine S is particularly high in the presence of a nonionic surfactant and has good color reaction contrast. In recent years, Japanese scholars have published over ten consecutive articles on the reaction of some metal ions with some chromogenic agents using octylphenol ethoxylates, Triton (Triton) X-100; Applied Triton X-100C_8H_ (17) (?)
