摘　　要：采用电化学方法检测甲基苯丙胺,探讨了不同扫描速度、初始浓度、pH值、电极处理温度及干扰物对检测的影响,获得了甲基苯丙胺电化学检测的最佳条件.结果表明,工作电极为掺硼金刚石薄膜电极,扫描速度为50-100 mV/s,初始浓度小于100 mg/L,pH=7.0及电极处理温度为100℃时,甲基苯丙胺的检测速度最快,检测结果最好,同时干扰物对于电化学方法检测甲基苯丙胺无明显影响.Electrochemical method was used to detect methamphetamine（ MA） and the effects of different detection conditions,such as the scan speed,the initial concentration of MA,pH value,electrode processing temperature and disruptors,on the electrochemical detection of MA were investigated to find out the optimal conditions for the electrochemical detection of MA. The results show that with BDD thin film electrode as the working electrode and at a scan rate of 50—100 mV/s,initial concentration of lower than 100 mg/L,pH = 7. 0 and electrode processing temperature of 100 ℃,the detection rate of MA is the fastest with best results,and the disruptors have no obvious effect on the detection of MA.
