建立毛细管电泳电化学发光法测定氟哌啶醇的新方法.考察了工作电极电位、磷酸盐缓冲液浓度及其pH值等对氟哌啶醇测定的影响.在优化实验条件下,氟哌啶醇浓度线性范围为0.01~10 mg·L^-1,检出限(3σ)为3.5μg·L^-1;相对标准偏差为1.6%(3.0 mg·L^-1,n=11).利用该法测定了人尿加标后氟哌啶醇的含量,回收率为95.0%~99.5%.
A novel method of capillary electrophoresis (CE) with tris (2,2'-bipyridyl)ruthenium ( I ) electrochemiluminescence (ECL) detection has been developed for the determination of haloperidol in human urine. The parameters such as work electrode potential,concentration and pH of phosphate buffer solution on effect of ECL intensity of haloperidol were investigated. Under optimized conditions,haloperidol concentration was linear with ECL peak area in the range of 0. 01 - 10 mg·L^-1. The detection limit (3a) for haloperidol was 3. 5 mg·L^-1,and the RSD was 1.6% for 3.0 mg·L^-1 haloperidol (n=11). The recoveries were between 95.0% and 99.5%.
