本文首次将亚硫酸钠化学除氧技术应用于β－环糊精诱导室温燐光（β－CD－RTP）法中，除氧简便快速（1～1．5min），测定了痕量二氢苊、芴、菲、7，8－苯并喹啉。1，2－二溴乙烷作重原子微扰剂，其用量减少到每10mL中5μL，体系基本澄清，pH≈6．8，分析特性优于通氮除氧技术所得结果。
In this paper, the first time sodium sulfite chemical deoxygenation technology was applied to β-cyclodextrin-induced room temperature phosphorescence (β-CD-RTP) method. The deoxygenation was simple and rapid (1 ~ 1.5min) Phenanthrene, 7,8-benzoquinoline. 1,2-dibromoethane as a heavy atom perturbation agent, the amount was reduced to 5μL per 10mL, the system was basically clear, pH≈6.8, the analytical characteristics superior to the results obtained through the nitrogen deoxygenation technology.
