    在进行矿井水中油类分析时，用正己烷作为萃取剂，以工作曲线代替标准曲线，从而使油平均回收率增加到96％以上。并在正己烷用量、水样预处理等测试参数选择上做了条件试验。

    The n-Hexane extraction was used in analysis on oil in mine drainage,and working curve was cover for standard curve.The result showed that average recovery rate of oil was over 96％. In this article conditional experiments on the amount of n-Hexane and water sample pretreatment for determining parameter were introduced.
