电感耦合等离子体发射光谱法测定煤灰成分研究

Study of coal ash constituents by electro-inductive coupling plasma spectrum emission

采用电感耦合等离子体发射光谱法测试煤灰中9种常量元素,提出了标准溶液和标准灰样两种工作曲线测定方法,对两种方法的检出限、重复性(精密度)、准确度比较的结果显示,由于后者与待测样品有相似的主体或成分特性,减少了因主体成分差异引起的谱线干扰等带来的系统误差,因此在准确度和精密度上更有优势,更适合于煤灰成分的测定。

Electro- inductive coupling plasma spectrum emission used for determination of 9 elements contained in coal ash,working curves of standard solution and standard ash sample proposed for determination,comparison of determined limit,reproduce- ability,preciseness,that,in view of the later being of the same main characteristics with the sample to be determined, systematic error reduced, thus, superior in preciseness and more suitable for determination of ash constituents.
