中文摘要: 采用碱熔方法来消解样品,用硅钼蓝分光光度法测定样品中二氧化硅含量,通过试验确定盐酸、乙醇的加入量和测定时波长的选择等,加入标准物质的回收率为 99.01%~100.05%,该方法准确度高,精密度好,操作简单,分析快速。测定范围 :10%~40%。
Abstract:The alkali fusion method is used to digest the sample, and the content of silicon dioxide in the sample is determined by si-Mo blue spectrophotometry. The addition amount of hydrochloric acid and ethanol and the choice of wavelength are determined by the test. The recovery rate of adding standard substances is 99.01%~100.05%. The method has high accuracy, good precision, simple operation and rapid analysis. The measurement range is 10%~40%.
