Gas chromatography method was developed for the determination of the water content in the ex-tractant by dissolving an internal standard in the extractant containing and the moisture content in the samples was calculated. The method is simple and easy to operate with short analysis time. The precision of the method (RSD) was≤5% , reproducibility (RSD) was≤10% , linear correlation coefficient R was ＞0. 99, and the average recovery rate was 101% (n =6, 94. 1%~105. 8% ).%将样品溶解于含有内标物的萃取剂中,采用气相色谱法测定萃取剂的水分含量,计算出样品中的水分含量.该方法简单易操作,分析时间短.方法的精密度(RSD)≤5％,重复性(RSD)≤10％,线性R＞0.99,平均回收率101％ (n=6,94.1％～ 105.8％).
