| Abstract: | Nine elements in calcium gluconate were simultaneously determined with ICP-AES. Major constituent interference was calibrated by matrix matching. The dissolution methods of samples, and the effects of matrix and acid conditions were also discussed. The detection ranges are 0. 0008%-0. 08% for Pb,0. 0001%-0. 01% for Cu,and Mg,and 0. 0003%-0.03% for As,CA, Ni,Cr,Fe,Ni. The recoveries are in the range of 95.8%-100. 0 %. The relative standard deviation are in the range of 0.16%-3.61%. The Results are satisfactory. |
