| Abstract: | A spectrophotometric method based on kalman filter was described for the simultaneous determination of trace As and P in the ion-associate complex compound with ethylrhodamine B. The interference from overlapping spectra was eliminated by the filtering of data. with no separation or masking. The proposed method was appiled to the analysis of Asand P in waters with satis factory results. |
