摘要

应用方波溶出伏安法研究了放线菌素D在KH2PO4-Na2HPO4缓冲溶液中于金电极上的电化学行为以及酸度、预富集沉积电位、预富集沉积时间、方波频率、方波幅度、电位增量等的影响,优化测定参数,建立一种直接测定放线菌素D的电分析测定方法.在0.1~10.0μmol.L-1浓度范围内,放线菌素D与其方波溶出伏安氧化峰电流呈良好的线性关系,相关系数0.9991,检测限1.0×10-8mol.L-1.

Abstract

The electrochemical behaviors of Actinomycin D(ACTD)at glod electrode were investigated by square wave stripping voltammeter in the KH2PO4-Na2HPO4 buffer solution(pH=5.90).The sensitive oxidation peak of ACTD was observed and the potential peak for ACTD is-0.17 V(vs.SCE).The Experimental parameters,such as pH value,amplitude,accumulation potential and time were optimized,and a direct electroanalytical method for determining ACTD was developed.The peak currents were proportional to the concentration of ACTD in the range of 0.1μmol·L-1~10.0μmol·L-1,and the linear regression coefficient equaled 0.9991.The detection limit for ACTD was 1.0×10-8mol·L-1.
