- 中文摘要: A new inhibitory reaction is proposed and a kinteic method developed for the determination of ultramicro amounts of Mo(VI) on the basis of its inhibitory activity in oxidation of trimethylenediamine – N,N,N¢,N¢-tetraacetic acid (TDTA) by KMnO4 in the presence of hydrochloric acid. Under optimal conditions the sensitivity of the method is 0.5 ng/cm3. The probable relative error is 2.9-3.5% for the concentration range 7.5-2.0 ng/cm3 of Mo(VI). The effect of certain foreign ions upon the reaction rate were determined for the assessment of the selectivity of the method. The selectivity of the method is relatively good. Kinetic equations were proposed for the investigated process. A method has been applied for determination of Mo(VI) in a certain kind of steel.
