乙二醇中控样品中钾含量测定的研究

Study on Determination of Potassium in Ethylene Glycol Central Control Sample

在乙二醇装置中,钾含量对于装置有着重要的指导意义,本论文中,分别建立了使用离子色谱(IC)法及电感耦合等离子体-原子发射光谱(ICP-AES)法测定乙二醇装置中控样品中钾的含量。对两个方法进行各方面的比较,两个方法操作简单,均能保证结果的准确性及精密度且方法间偏差通过。各实验室可根据自身条件选择相应的方法来进行样品分析。

In the ethylene glycol device,potassium content has important guiding significance for the device.In this paper,ion chromatography(IC)method and inductively coupled plasma atomic emission spectrometry(ICP-AES)method were established to determine potassium content in the central control sample of ethylene glycol device.Comparing the two methods in all aspects,the two methods are easy to operate,which can ensure the accuracy and precision of the results,and the deviation between the methods is acceptable.Each laboratory can choose the corresponding method to analyze the samples according to its own conditions.
