钢铁中硅含量测定方法的研究

摘要

采用还原型硅钼酸盐光度法对钢铁中硅含量进行了实验测定，根据测定原理，介绍了试料分解和试液制备的方法，并对最低检出限、精密度、准确度进行了分析，指出实验测定值均在标准样品保证值范围内。%This paper made experimental determination to silicon content in iron and steel using reduced silicon molybdate spectrophotometry method,based on the test principles,introduced the sample decomposition and solution preparation method,and analyzed the lowest detection limit,precision,accuracy,pointed out that the experimental values were in the range of standard samples guaranteed value.
