摘要
讨论了用毛细柱气相色谱法测定废水中三氯乙醛的方法。该方法用(2+1)石油醚-乙醚萃取废水中的三氯乙醛,方法的相对标准偏差4.9％,回收率91.2％～101.1％,最低检出限4×10^(-2)ng。
This paper studied a CGC method for determining chloral hydrate in wastewater. The preceding disposal of the method is using (2 + 1) petroleum benzine-diethyl ether to extract chloral hydrate. RSD is 4. 9% and recovery rates are 91. 2%-101. 1%. The detection limit is 4×10-2ng.
