Abstract: The present paper covers the simultaneous determination of copper and cobalt by pHgradient technique with PARas the chromogenicreagentPartial least squares (PLS) was used for calibration and prediction, and satisfactory results were achievedCompared with principal component regression (PCR) and multi-linear regression (MLR), the result of PLSis better.
