摘要
结合GB/T3558—2014煤中氯的测定方法中的高温燃烧水解-电位滴定法测定煤的Cl含量,简要说明使用此法的标准、原理及测定步骤。主要利用煤样在O2和水蒸气中燃烧水解释放出的全部Cl转移到冷凝液中,并用AgNO_3滴定,以滴定终点AgNO_3的用量来计算煤的Cl含量,这种方法快捷、方便,测得的结果也相对准确。
Combined with high temperature combustion hydrolyzing electric potential titration method for chlorine determination in coal of GB/T3558-2014 method for determination of the chlorine in coal, this paper made brief description of its standard,principle and determination steps the method of. This method mainly made All chlorine that were released in hydrolyzing of coal sample burn in the presence of O_2 and steam water were transferred to condensate, and then AgNO_3 was used to titrate amount of AgNO_3 in the end to calculate the Cl content of coal. This method is fast, convenient and its measuring results are relatively accurate.
