摘　　要：研究了肼对中性红与亚硝酸根之间反应的抑制作用,建立了动力学光度法测定肼的新方法,方法的线性范围为0.15～1.0mg/L,检出限为0.10mg/L.应用于水样中肼的测定,结果满意.A sensitive kinetic method for the determination of hydrazine is described. This method is based on the inhibitory effect of hydrazine on the reaction of neutral red with nitrite in acidic medium. The decolorization of neutral red by the reaction with nitrite was used to monitor the reaction spectropno-toroetrically at 540 ran. Hydrazine can be determined in the range of 0.15-1.0 mg/L, and the detection limit is 0.10 mg/L. The method has been used to detennine hydrazine in water samples with satisfactory results.
