基于苄丝肼对鲁米诺-铁***发光体系的增强作用,首次建立了苄丝肼的流动注射化学发光分析法.在优化的实验条件下,该方法的线性范围和检出限分别为0.01-1.0μg/mL和0.9 ng/mL,对0.10 μg/mL苄丝肼的相对标准偏差为2.4%(n=11).将其应用于加标尿样中苄丝肼含量的测定,结果令人满意.

A novel method for the determination of benserazide based on the enhancing effect of benserazide on luminol - potassium ferricyanide chemiluminescence system in alkaline solution is developed by flow-injection chemiluminescence method. The detecting parameters, such as the sampling time and dosage of luminol, potassium ferricyanide and sodium hydroxide, were optimized by orthogonal array designs. Under the optimum conditions, the emission intensity is proportional to the concentration of benserazide in the range of 0.01-1.0μg/mL. The detection...
