摘要
在环糊精诱导室温燐光法(CD-RTP)中,常用的重原子为链状卤代烷烃如1,2-二溴乙烷、1.2-二溴丙烷等。本文首次在7-甲基喹啉的β-CD-RTP 分析中应用了溴代环已烷作重原子,体系可不经除氧直接进行 RTP 测定。7-甲基喹啉的分析线性范围、检出限、相对标准偏差均与常规的以1,2-二溴丙烷为重原子的 CD-RTP 测定法相当,而后一种方法必须采用通氮除氧操作。
In this paper,bromocyclohexane is originally used to replace straight chain al- kane halides 1,2-dibromoethane and 1,2-dibromopropane(DBP)as heavy atom perturber for β-cyclodextrin induced room temperature phosphorimetry(CD-RTP)of 7-methylquinoline. The RTP intensity of 7-methylquinoline is conveniently detected without nitrogen purging The experimental results such as linear ranges,detection limits and rlative standard de- viation for the determination of 7-methylquinoline are similar to those obtained from the system using DBP as heavy-atom perturber in which nitrogen purging is required.
