【摘要】 <正> 8-羟基喹啉和8-羚基喹啉-5-磺酸（H₂QS）用于锌的荧光分析已有报道。史慧明和喜纳兼勇等分别研究了阳离子表面活性剂CTMAB及Zeph对Zn-H₂QS体系荧光反应的影响,可使灵敏度提高三倍左右。我们用7-碘-8-羟基喹啉-5-磺酸（H₂QSI）作光试剂,试验不同表面活性剂对Zn-H₂QSI体系的增敏作用,实验结果表明,只有阳离子表面活性剂CTMAB和Zeph的增敏效果最好,灵敏度提高约六倍,达2×10^-3μg Zn/ml。本文选择Zn-H₂QSI-CTMAB体系进行试验,找出三元配合物的最佳生成条件,确定更多还原

【Abstract】 The sensitization of various surfactants on fluorimetric reaction of Zn and H₂QSI has been compared, and the optimum conditions of fluorimetric determination of Zn have been established. CTMAB and Zeph are the best. The sensitivity of reaction is increased in sixfold in the presence of CTMAB. Zinc content in Magnesium alloy and Chrome alloy was determined with sat-isfactory results.更多还原
