摘要

使用溴酚蓝修饰的玻碳电极,以快速循环伏安法测定维生素C片剂中抗坏血酸含量并优化实验条件.结果表明,溴酚蓝(BPB)修饰玻碳电极用于抗坏血酸含量的分析,有良好的稳定性和抗干扰能力.在0.0050~0.1500 g.L-1浓度范围内,峰电流与浓度呈良好的线性关系,R=-0.9991,检出限为0.0010 g.L-1,结果令人满意.

Abstract

The content of ascorbic acid of(vitamin C) was analyzed by using fast cyclic voltamment with bromophenol blue(BPB) modififed GC-electrode,and which experimental conditions were optimiged.The results showed that the BPB modified GC-electrode had the good stability and anti-jamming faculty for analysing the content of ascorbic acid.A linear relationship between the peak current and concentration of vitamin C in the range of 0.0050~0.1500 g·L-1 was obtained,which related coefficient and the detection limit are-0.9991 and 0.0010 g·L-1,respeclively.The method has satisfactory results.

Key words： GCE; bromophenol blue; vitamin C; fast cyclic voltammetry
