| Abstract: | It was reported that in the ICP-AES determination of microamounts of antimony and tin in ferromolybdenum, charge injection device (CID) was used as detector in the measurement. The optimum analytical conditions (i.e. the choice of analytical wavelength the rationization of sample dissolution and etc) and the working parameters of the instrument were studied thoroughly. As a result of the study of the interference of matrix components (Mo and Fe) to the determination of Sb and Sn, it was ascertained that in the preparation of calibration curve, about 40% (mass percentage) of pure iron should be added as a correction for its matrix interference. Limits of detection for Sb and Sn were found to be 0.0011% and 0.004% respectively. Recoveries obtained were in the range of 99% to 103%. |
