苯基萤光酮是不含-COOH及-SO_3H的酸性染料,试剂中的亲水基团少,与金属离子生成的络合物水溶性小。一般说来,测定时加入动物胶作为分散剂,有色络合物才不会沉淀析出。若加CPB或CTMAB等阳离子表面活性剂,在适当的条件下,灵敏度有很大提高,故广泛地应用于Ti、Sn、Zr、Mo等高价金属离子的测定。 Triton X-100是非离子型表面活性剂,它同阳离子表面活性剂一样,有胶束增敏增溶
Phenylfluorone is an acidic dye that does not contain -COOH and -SO_3H. The reagent has few hydrophilic groups and has a small water-solubility with complex formed from metal ions. In general, the determination of animal glue added as a dispersant, colored complex will not precipitate precipitation. If plus CPB or CTMAB and other cationic surfactants, under the appropriate conditions, the sensitivity has greatly improved, it is widely used in the determination of Ti, Sn, Zr, Mo and other high-priced metal ions. Triton X-100 is a non-ionic surfactant, which, like cationic surfactants, has micellar sensitization and solubilization
