A Standard Addition Method for ICP-AES Determination of Si and Ti in Corundum with High-Frequency Fusion

摘要: 以Li2B4O7 为熔剂高频电感熔样,等离子体发射光谱标准加入法测定了刚玉中的硅和钛。方法的检出限Si为0. 05mg/L,Ti为0. 02mg/L;线性浓度上限Si为40mg/L,Ti为80mg/L;回收率为95. 2% ~104. 3%;RSD(n=6)为0. 88% ~1. 36%。

Abstract: A standard addition method for determination of Si and Ti in corundum by ICP-AE S was studied and fused samples with high-frequency was applied. The detection limits are: 0.05 mg/L for Si,0.02 mg/L for Ti; the upper limit for the range of linearity are
