摘要
为进一步提升煤炭中氮含量测定结果的准确性,以当前常用的半微量开氏法为实验方法,结合具体的实验流程,对消化反应、蒸馏环节和滴定环节可能产生误差的原因及解决措施进行了探究,同时也阐述了部分实验细节中的误差及改进对策,以期为今后的类似实验工作提供参考借鉴.
Abstract
In order to further improve the accuracy of nitrogen content determination in coal,the commonly used semi micro Kelvin method was used as the experimental method,combined with specific experimental procedures,to explore the reasons and solutions for possible errors in digestion reaction,distillation process,and titration process.At the same time,some errors in experimental details and improvement strategies were also explained,in order to provide reference for similar experimental work in the future.
