Abstract
Aiming at the problems of low sensitivity and poor selectivity of spectrophotometry and titration in the analysis of hy-droxylamine nitrate content in energetic material production wastewater,a high sensitivity analysis method based on gas chroma-tography tandem mass spectrometry(GC-MS)was developed for the determination of trace hydroxylamine nitrate in water.Through acetone derivatization,hydroxylamine nitrate reacted with acetone to produce acetone oxime which was easy to be test-ed by gas chromatography.The derivatization conditions and GC-MS parameters were optimized,and N,N-dimethylnitrosamine(NDMA)was used as the internal standard for quantitative analysis.The results showed that the linear relationship of hydroxyl-amine nitrate in the linear range(R2>0.999)was good,the detection limit was 0.015 mg·L-1,the recovery rate was 95%-108%,and the relative standard deviation was 3.6%-5.7%.This method has been successfully applied to the analysis of industrial waste water.It has the advantages of simple operation,high sensitivity and strong anti-interference ability.It provides an efficient and accurate analytical method for the monitoring of hydroxylamine nitrate in environmental water.关键词
