离子色谱法测定煤矿水中钠离子

Determination of Sodium Ion in Coal Mine Water by Ion Chromatography

对离子色谱法测定煤矿水中的钠离子灵敏度、精密度,准确度、优缺点以及可行性进行了分析。结果表明,该方法测定煤矿水,相对标准偏差和加标回收率均能达到质量控制要求,且线性范围宽、干扰少,不受pH影响,缺点是耗时长,因此适合测定干扰多基体复杂的煤矿水。

The sensitivity,precision,accuracy,advantages,disadvantages and feasibility of ion chromatography for the determination of sodium ion in coal mine water were analyzed.The results show that the relative standard deviation and spiked recovery of this method can meet the requirements of quality control.It has wide self linear range,less interference and is not affected by pH.The disadvantage is that it takes a long time.Therefore,it is suitable for the determination of coal mine water with multiple interference and complex matrix.
