【 摘 要 】

A solution absorption/spectrophotometry method was established for the determination of hydrazine in air. The collection efficiency of hydrazine in air under different sampling conditions was analyzed. The determination results were compared with those of the national standard method. We found that the collection efficiency of hydrazine gas was high with the solution absorption method; the relative standard deviation of determination results within this method was less than 5% and the relative error between the two methods was less than 2%. The proposed method had the characteristic of fast and relatively simple operation with high accuracy and reliability.
