【摘要】 采用固定相为Chromosorb 103和101的气相色谱法,直接分析水中的低碳含氮化合物。检测限量在10ng以下,相对误差最大为4.9％。同时,对推进剂废水中十种含氮化合物进行了定性、定量分析,具有快速、简便的优点。更多还原

【Abstract】 A packed column GC method was proposed for direct analysis of N-eon-taining low carbon compounds at ppm levels in wastewater, with Chromosorb 103 and 101 as the stationary phase. The detection limit was below 16 ng with a relative error of ±4.9%. By this method, the results of qualitative and quantitative analysis of 10 compounds in the wastewater are presented,更多还原
