| Abstract: | :The conditions for colouration reaction of Diphenyl thiocarbazone and Ph(11) or Cd(Ⅱ) isstudied in the medium of Na2B4O7-NaOH solution (pH=9.0). The disruption is resolved by C3H6(OH)3.K2C2O4 CHOH(CH2OH)2, and H2O2. A principal component analysis(PCA) is applied to simultaneousdetermination of Ph(Ⅱ) and Cd(Ⅱ) in water. Recover of Ph(Ⅱ) is 96.7%-109.4%, and recovery ofCd(Ⅱ) is 98.6%-106.3%. |
