芦荟大黄素1.5阶微分阳极溶出伏安法测定及电化学性质研究
, PP. 487-493
Keywords: 芦荟大黄素,伏安行为,微分阳极溶出伏安法,测定
Abstract:
研究了芦荟大黄素在以0.1mol/LHAc(pH2.89)为支持电解质,玻碳电极为工作电极的吸附伏安行为.结果表明芦荟大黄素存在一个准可逆的双电子转移过程,其峰电流Ip和峰电位Ep与溶液pH值有关.同时还建立了用1.5阶微分阳极溶出伏安法测定含量的新方法.在-0.80V(vs.SCE)电位下富集,可得一灵敏的微分阳极溶出峰,峰电位Ep为-0.38V,峰电流Ip与芦荟大黄素的浓度在2.0×10-7～8.0×10-6mol/L范围内成线性关系,最低检出限为1.0×10-7mol/L.该法用于含有芦荟大黄素体系的测定,具有简便、快速、准确等优点
