阻抑动力学荧光分析法测定痕量苯肼
Fluorimetric kinetic method for determination of phenylhydrazine based on the inhibitory effect
【摘要】 基于苯肼对吡咯红Y与亚硝酸根反应的抑制作用,建立了一种新的测定痕量苯肼的阻抑动力学荧光分析法。该方法的检出限为7.2ng mL,线性范围为8.0~60ng mL。直接用于环境水样中苯肼的测定。
【Abstract】 A simple and sensitive fluorimetric method for determination of phenylhydrazine was described. This method was based on the inhibitory effect of phenylhydrazine on the reaction of pyronine Y with nitrite in sulfuric acid medium. The detection limit for phenylhydrazine was 7.2 ng/mL, the linear range of the determination was 8.0~60 ng/mL. The method was used to determine phenylhydrazine in water samples with satisfactory results.
