| 摘 要： | 用气相色谱对二溴乙烷标准溶液的稳定性进行了研究。本文考查了二溴乙烷1、10、50、100、200及400μg/L 5个浓度的标准溶液的稳定性,实验结果表明：在配制保存得当的条件下可保存2.5个月;溶剂挥发对二溴乙烷标准溶液的浓度影响较大。本文为确定二溴乙烷标准溶液的有效期提供了理论依据。

| Abstract: | The stability of Ethylene Dibromide standard solution was studied by GC-ECD.Six concentrationsof Ethylene Dibromide（1,10,50,100,200 and 400 μg/L） were analyzed.The results demonstrated that ethylene dibromide standard solution was stable when it was properly stored in refrigerator for no less than 2.5 months,however,solvent volatilization affected the concentration of standard solutions significantly.Based on the study,the period of validity of ethylene dibromide standard solution can be set theoretically. |
