| 摘 要： | 应用线性扫描极谱法研究芬布芬的电化学行为.在0.2mol.L-1Na2HPO4-KH2PO4缓冲溶液(pH6.86)中,芬布芬于-1.38V(vs.SCE)处产生一灵敏的吸附波,其一次微分线性扫描峰电流与芬布芬浓度呈良好的线性关系,浓度范围1.6～200.0mg.L-1,相关系数r=0.9958(n=10),检出限为0.8mg.L-1.以80.0mg.L-1芬布芬溶液作6次平行试验,RSD为0.73%,回收率在97.7%～109.2%之间.芬布芬的此一电化学特性可用于其片剂含量测定.

| Abstract: | The electrochemical behavior of fenbufen had been studied by linear scanning polarographic method.In 0.2mol L-1 phosphate buffer solution(pH6.86),a sensitive reductive wave of fenbufen appeared at-1.38 V(vs.SCE).The linear relationship between the peak current and the fenbufen concentration in the range of 1.6～200.0 mg·L-1(r=0.9958,n=10)were observed,the detection limit of this method was 0.8 mg·L-1.RSD is 0.73%,found from the data of 6 independent determinations at the concentration level of 80.0 mg·L-1.recovery ratio is 97.7%～109.2%.This fenbufen's electrochemical characteristic property may be used to determining the contents of tablets. |
