摘要
分析了库仑滴定法测定火电厂煤中全硫时其准确度和精密度的影响因素,通过仪器定期标定与维护、标准煤样监控、平行样测定、定期复检、不同仪器对同一待测煤样测定对比等方法对全硫测定过程进行控制,以确保煤中全硫测定的准确性。
The influencing analyzed in this paper factors on the Many measures accuracy and precision of total sulfur determination in coal labs of power plants were such as regular calibration and maintenance of instrument, standard coal sample monitoring, parallel sample determination, regular review and contrast testing with different instruments, were adopted to contro the process of total sulfur determination, which could ensure the accuracy of the determination
