The ïĆāĆĀ¢-correction method for the spectrophotometric determination of zinc based on colour reaction with PAR is proposed. The use of this modification improved the precision and accuracy of the method. Using the ïĆāĆĀ¢-correctionmethod zinc was determined in range 0.5-10ppmwith limit of detection 0.07ppm. The RSD%of determinationwas 0.35%at 5ppmlevel.
