| Abstract: | The present paper covers the simultaneous determination of copper and cobalt by pH gradient technique with PAR as the chromogenic. reagent. Partial least squares (PLS) was used for calibration and prediction, and satisfactory results were achieved. Compared with principal component regression (PCR) and multi-linear regression (MLR), the result of PLS is better. |
