用硅钼蓝分光光度法测定煤灰中二氧化硅的问题探讨

Discussion on determination of silica in coal ash by silicon molybdenum blue spectrometric method

主要介绍硅钼蓝分光光度法测定煤灰中的二氧化硅，针对GB／T1574—1995中的试验方法，利用标准灰样做对照，对国家标准中的几个易被忽略而又易影响准确性结果的因素进行了合理的改进。

Silicon molybdenum blue spectrometric method was used to determine silica in coal ash. According to test method in GB/T 1574-1995, comparing to standard ash sample, the improvement of some factors that were easy to be neglected but influenced veracity of results were presented in this paper.
