| 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 40 mg/L for Si and 80 mg/L for Ti;the precision is 0.88%~1.36% ( RSD,n=6)with a satisfactory recovery 95.2%~104.3%. |
