摘    要:基于胶束介质中硝苯地平对碱性鲁米诺-过氧化氢化学发光体系的增敏作用,结合反相流动注射技术,建立了流动注射化学发光分析法测定硝苯地平的新方法.硝苯地平浓度在3.5×10-10~4.0×10-8 g·mL-1范围内时,化学发光强度与硝苯地平的浓度呈良好的线性关系,其相对标准偏差为1.4%(n=11,c=3.5×10-9 g...

关 键 词:硝苯地平  反相流动注射  化学发光  胶束增敏

Abstract:A novel chemiluminescence system coupled with reverse flow injection technique has been developed for the determination of nifedipine.It was found that the chemiluminescence reaction of luminol with hydrogen peroxide in sodium hydroxide media could be strongly enhanced by nifedipine in the presence of cetyl pyridinium chloride.Then a flow injection chemiluminescence detection was developed for the determination of nifedipine.Under the optimum conditions,the chemiluminescence instensity and the contents of n...
Keywords:nifedipine  reverse flow injection  chemiluminescence  micellar-enhanced
