The chromatographic behaviour of eighteen s-triazine derivatives has been studied in a reversed-phase system with a Separon SIC 18 stationary phase and a mobile phase of aqueous sodium dihydrogenphosphate and methanol. The dependences of the capacity factors on the methanol content, the pH and the ionic strength have been obtained. Ultraviolet photometric detection can generally be used whereas amperometric detection with a carbon-fibre array electrode is useful for selective detection of s-triazine hydroxy derivatives, but with a sensitivity poorer than that of photometric detection. The method has been applied to a study of the photolysis of s-triazines and the effect of the substituents and the pH on the photolysis rate.
研究了十八种均三嗪衍生物在具有Separon SIC 18固定相以及磷酸二氢钠水溶液和甲醇流动相的反相体系中的色谱行为。获得了容量因子对甲醇含量、pH值和离子强度的依赖性。通常可采用紫外光度检测,而使用碳纤维阵列电极的安培检测对于均三嗪羟基衍生物的选择性检测很有用,但灵敏度低于光度检测。该方法已应用于均三嗪光解以及取代基和pH值对光解速率影响的研究。
