近年来,对铍(Ⅱ)-铬天青 S-阳离子型表面活性剂体系的分光光度性质以及盐类对该体系的影响已有报导。但对于铍(Ⅱ)-铬天青 S-非离子型表面活性剂体系的分光光度性质研究较少,且对应用未作详细介绍。我们详细研究了 Be(Ⅱ)-CAS-TX-10体系的分光光度性质,试验表明,这一体系具有很高的灵敏度,其三元络合物吸收峰相对于二元络合物吸收峰发生较大红移,从545nm 位移到615nm。
In recent years, the spectrophotometric properties of the beryllium (II) -chromium azide S-cationic surfactant systems and the effects of salts on the system have been reported. However, there are few studies on the spectrophotometric properties of beryllium (II) -chromium azide-non-ionic surfactant systems, and no detailed application is given. We studied in detail the spectrophotometric properties of the Be (II) -CAS-TX-10 system. The experimental results show that this system has a high sensitivity. The absorption peak of the ternary complex relative to the absorption peak of the binary complex occurs Large redshift shifted from 545 nm to 615 nm.
