Determination of superoxide anion radicals in sodium hyposnlfite solution by chemiluminesceot methods(连二亚硫酸钠体系中超氧阴离子的化学发光法检测)

建立一种以luminol试剂为发光底物,检测连二亚硫酸钠水溶液体系产生的超氧阴离子自由基的化学发光法.研究表明,当luminol的浓度为0.05 mg/mL,连二亚硫酸钠浓度为0.012 mg/mL,体系pH=10.3时,可得最佳测定条件.分别测定了茶多酚、芦丁、槲皮素和抗坏血酸清除超氧阴离子自由基()的能力.结果表明此方法操作简便、测量快速,能用于天然活性物质清除超氧阴离子能力的测定和清除自由基机理的研究....
