砷钼蓝分光光度法测定煤中砷的影响因素分析

The analysis on influencing factors arsenic measurement in coal through arsenic molybdenum blue spectrophotometric method

结合煤中砷的测定原理,从燥样搅拌、煤样灼烧及灼烧物溶解等方面探讨了煤样处理时应注意的事项,并从溶液的保存与配制、煤样处理酸化、比色等试验步骤以及关于高砷煤测定的几个方面详细阐述了砷钼蓝分光光度法测定煤中砷的影响因素,并提出了相应的处理办法。

Combining with arsenic measuring principle in coal,and from aspects such as coal sample stirring,coal sample combustion and burning things dissolution,some notices when dealing with coal sample were discussed,and moreover,from some procedures like solution preservation and preparation,coal sample processing and acidification,colorimetric and some aspects related to high arsenic coal,the influencing factors in determination of arsenic in coal using arsenic molybdenum blue spectrophotometric method were discussed,the corresponding measurements were proposed as well.
