本文用等摩尔系列、摩尔比、制备法研究了 Al—CAS—CTMAB 多元络合物的组成,得到:Al∶CAS∶CTMAB=1∶3∶2、1∶3∶4、1∶3∶10、1∶3∶2和1∶3∶4多元络合物是计量组成络合物,它们均难溶于水。当 CTMAB 浓度较大时,以1∶3∶4络合物为中心,外绕6个 CTMAB 胶束,形成1∶3∶10高次胶束络合物,并由胶束增溶而溶于胶体溶液中。灵敏度的提高和最大吸收波长移动是由于逐级形成络合物。并提出了可能的络合物模型。
In this paper, the composition of Al-CAS-CTMAB multicomponent complex was studied by equimolar series, molar ratio, and preparation method. The results showed that: Al: CAS: CTMAB = 1: 3: 2, 1: 3: 4, 1: 3: , 1: 3: 2, and 1: 3: 4 multiple complex are metered compositional complexes that are poorly soluble in water. When the concentration of CTMAB is larger, the 6 CTMAB micelles are wound around the 1: 3: 4 complex, forming a 1: 3: 10 high order micellar complex and solubilized by the micelles Colloidal solution. The increase of sensitivity and the shift of the maximum absorption wavelength are due to the gradual formation of complexes. And proposed a possible complex model.
