尽管各种表面活性剂在分光光度法中的应用日益广泛,但对混合表面活性剂的研究仍报导较少。Watanade曾研究了在阴离子和非离子型混合表面活性剂存在下,用1-(2-吡啶偶氮)-2-萘酚测定钴,郑用熙等用阴-阳混合型表面活性剂用铬天青S测定铝,戚文彬等研究了阴离子和非离子表面活性剂混合液在Ag~+-5-Cl-PADAB体系中的协同增色作用。作者曾在两性、非离子表面活性剂存在下比较满意地用铬天青S测定了不同材料中的Sc、U,并发现除两性表面活性剂外,阳离子与非离子表面活性剂亦可形成混合胶束,对体系有较好的增敏、增溶及增稳作用。目前阳离子表面活性剂应用广泛,如能深入研究这两种混合表面活性剂的作用及有关机理,并推广应用,将对胶束增溶分光光度法有所促进。本文是在Al、Be、Fe、Sc同铬天青S、阳
Despite the increasing use of various surfactants in spectrophotometry, less research has been reported on mixed surfactants. Watanade has studied the use of 1- (2-pyridylazo) -2-naphthol in the presence of anionic and non-ionic mixed surfactants for the determination of cobalt, Cheng Yong Xi and other mixed with anion-cation surfactant with chrome azure S determination of aluminum, Qi Wenbin, etc. studied the anionic and nonionic surfactant mixture Ag ~ + -5-Cl-PADAB synergistic coloration. The authors have been more satisfactory in the presence of amphoteric, non-ionic surfactants with chromium Azure S measured in different materials Sc, U, and found that in addition to amphoteric surfactants, cationic and non-ionic surfactants can also form a mixture Micelles, the system has a better sensitization, solubilization and stabilizing effect. At present, cationic surfactants are widely used. If we can further study the action and related mechanism of these two surfactants and promote their application, they will promote micellar solubilization spectrophotometry. This article is in Al, Be, Fe, Sc with chrome azure S, Yang
