摘　　要：本文用单扫描极谱法(LSP)研究了氯诺昔康的极谱行为。实验发现,以0.04mol·L-1的B-R缓冲溶液为底液,氯诺昔康在-1.87V(vs.SCE)处有一个灵敏的二阶导数极谱峰,其二阶导数极谱峰峰高与氯诺昔康的浓度在1.0×10-6mol·L-1～2.0×10-5mol·L-1范围内呈较好的线性关系,相关系数为0.9985,检出限为0.04753mol.L-1。实验结果显示,该方法测定氯诺昔康快速、准确、可靠。In this paper,single-sweep polarographic method for the determination of lornoxicam has been developed. In 0.04 mol／5L-1 B-R solution,it was found that a sensitive polarographic wave of lornoxicam was presented at about-1.87 V （vs.SCE）. This response was linear with the concentration of lornoxicam from 1.0×10-6 mol／5L-1 to 2.0×10-5 mol／5L-1 （r=0.9985）. The detection limit was 0.04753 mol／5L-1. The results show that the method is accurate,feasible and could be used to analyze specimen of lornoxicam.
