摘要：

A simple continuous-flow chemiluminometric method for the determination of 0.05-10 mu g/ml of sodium nitroprusside is described. The method is based on the catalyses of luminol oxidation by hydrogen peroxide in alkaline medium. The method is sensitive and requires no sample pre-treatment and solutions can be analysed at a rate of 40 samples/hr with a relative error of about 1.18%. The method was satisfactory for the determination of sodium nitroprusside in a pharmaceutical preparation. The effect of some potential interferents is described.
