| Abstract: | Under the optimum experimental conditions (i. e., pH=1.6, c KI=10.6 mmol/L,  =5.4 mmol/L,  =1.30 mmol/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∼120×10−6mol/L respectively. This method was applied to the examination of the industrial waste water, and the recovery ratios were found to be in the range of 101% and 107%.
