| Abstract: | Under the optimum experimental conditions (i. e. ,pH = 1.6, cKI = 10.6 mmol/L, cH2O2 = 5.4 mmol/L, cC6H8O6 = 1.30mmol/L) derived from simplex operations, trace molybdenum(Ⅵ) was determined through the agency of its catalytic effect on the reaction of H2O2 with I- in acid medium. The detection limit and linear calibration range of molybdenum were obtained as 0.5 × 10-6 mol/L and 0.5 × 10- 6 ～ 120 × 10- 6 mol/L respectively. This method was appli ed to the examination of the industrial waste water, and the recovery ratios were found to be in the range of 101% and 107%. |
