锆(铪)与铬菁R的二元络合物在pH=1.8—2.5时生成红色络合物,其λ_(max)=540nm,ε=6.0×10~4,但锆(铪)——铬菁R——表面活性剂三元体系尚未见报道。本实验在二元络合物的基础上,研究了锆(铪)铬菁R—阳离子表面活性剂三元络合物。实验结果表明:在pH=2.5—3.2范围内,锆(铪)与铬菁R—氯化十四烷基吡啶形成紫色络合物,λ_(max)=580nm,ε=9.6×10~4,灵敏度比相应的二元络合物提高了60％,并且可在水相中直接进行测定,可视为测定锆(铪)的较好方法之一。
The binary complex of zirconium (hafnium) and chromium cyanine R produces a red complex at pH = 1.8-2.5, with λ max = 540 nm and ε = 6.0 × 10 4, but zirconium (hafnium) Chrome cyanine R - surfactant ternary system has not been reported. In this experiment, based on the binary complexes, zirconium (hafnium) chromate R-cationic surfactant ternary complex. The experimental results show that zirconium (hafnium) forms purple complex with chrysene R-tetradecylpyridinium chloride at λ = 2.5-3.2, λ max = 580nm, ε = 9.6 × 10-4, Sensitivity than the corresponding binary complex increased by 60%, and can be measured directly in the water phase can be considered as zirconium (hafnium) one of the better ways.
