标准摘要
[中文适用范围]： 本标准规定了一种还原钼磷酸盐光度法，用于测定硬煤、褐煤和焦炭中总磷的质量分数。规定了两种磷溶解方法：用酸从煤或焦炭灰分中提取磷，或用酸反复氧化煤或焦炭以除去含碳物质。 [外文原描述]： This document specifies a reduced molybdophosphate photometric method for the determination of the total phosphorus mass fraction of hard coal, lignites and coke. Two methods for taking the phosphorus into solution are specified, namely extraction from the coal or coke ash with acid or by repeated oxidation of the coal or coke, by acid, to remove carbonaceous matter.
英文名称Coal and coke — Determination of phosphorus — Reduced molybdophosphate photometric method
