摘要: |
介绍了用一甲肼浓缩采样管采集空气中三肼混合气体,用分光光度法分别测出肼、一甲肼和偏二甲肼各组分的含量。测定结果通过标准气验证,相对误差小于17%,各组份回收率均大于80%。本方法适用于空气中低浓度三肼废气的测定。 |

Abstract: |
As the sample of N 2H 4,MMH and UDMH mixture gas in air is collected by sampling tube for concentration MMH,the concentration of N 2H 4,MMH and UDMH is measured simultaneously by spectrophotometer.The experimental results show that the relative error of measurement is less than 17%,and recovery rate of every components is greater than 80% by comparison with the check of standard mixture gas.This method is suitable for detection of low concentration hydrazine fuel waste gas in air |
