| Abstract: | A method of correcting spectral interferences in ICP-AES by Kalman filtering technitlue (KF) is described and a microcomputer program of "ICPKF" is developed with Language C. The interferences of Al on La and Ph, Ti on Bi and Co, and Pt on V are studied as some typical examples. Some optimal operating conditions and model parameters are also investigated. The results of the proposed method are shown to compare favorable with that of onaipeak or off-peak method, and it can be used in correcting each type of spectral interferences especially for very low analyte concentration. |
