离子色谱法与国标法测定煤中碳酸盐二氧化碳含量对比分析

Comparative Analysis of Ion Chromatography and National Standard Method for Determining Carbonate Carbon Dioxide Content in Coal

为进一步探究煤炭中碳酸盐二氧化碳含量的精准测定路径,本次基于GB/T 218—2016方法进行测定,并同时引入离子色谱法进行对比分析,明确了两种测定方法所需的实验材料、设备与实验流程,并将测试结果进行对比分析。分析结果显示,离子色谱法在精密度和准确度等关键指标上更具优势,因此将成为今后煤炭中碳酸盐二氧化碳含量测定的主要方法。

In order to further explore the precise measurement path of carbonate carbon dioxide content in coal,this study was based on the GB/T 218-2016 method for measurement,and ion chromatography was introduced for comparative analysis.The experimental materials,equipment,and process required for the two measurement methods were clarified,and the test results were compared and analyzed.The analysis results show that ion chromatography has advantages in key indicators such as precision and accuracy,and will therefore become the main method for determining the carbonate carbon dioxide content in coal in the future.
