摘要：
A novel flow-injection chemiluminescence ( CL) system for the determination of isoniazid was proposed. It is based on the oxidation reaction between potassium permanganate and isoniazid in the basic medium of sodium hydroxide. The system offers good selection,great sensitivity with a linear range of 0.01 similar to 5. 0 mg/L. The relative standard deviation (n = 11) is 2.5% for 0.5 mg/L isoniazid and the detection limit is 7.0 mug/L. The method has been applied to the determination of isoniazid in tablet samples with satisfactory results.
