【摘要】 基于硝普钠在碱性介质中催化过氧化氢氧化鲁米诺的化学发光反应，建立了一种流动注射化学发光测定硝普钠的新方法。本方法分析速度快，灵敏度高，在２×１０－７～１×１０－４ｍｏｌ／Ｌ范围内，化学发光信号与硝普钠的浓度呈线性关系，对２×１０－７ｍｏｌ／Ｌ硝普钠的１１次平行测定的相对标准偏差为１．５％。注射用硝普钠标准加入回收实验结果均令人满意。更多还原

【Abstract】 A flow injection chemiluminescence method for the determination of sodium nitroprusside has been developed.The method is based on the catalytic oxidation of luminol by hydrogen peroxide in alkaline medium.The method is sensitive and can be run at a rate of 40 samples/h,It has been used to determine sodium nitroprusside in pharmaceutical preparation.Some potential interference substances also were tested.更多还原
