A KINETIC SPECTROPHOTOMETIC METHOD FOR DETERMINATION OF TRACE MANGANESE

Miao JianYing;Yu XinWu;Zhang Weihua;Wan Ailing (Baoji Teachers College)(Hubei Normal University)  
A new method has been studied in this paper based on the fact that trace Mn(Ⅱ) in a solution of KHC8H4O4──NaOH(PH4.8)catalyzes the discoloring reaction of Eriochrome black T by KIO4.The apparent activation energy of the reaction is 60.18 KJ. mol-1 , the apparent rate constant is 7.39×10-3min-1 and the half life period(T1/2) is 93. 8 min. and it is a first order reaction. The detection limit is 1. 45×10-10g. ml-1 The range of measurement is 0~0. 1 ugMn(Ⅱ)/25ml,The method has been used ror determining trace Mn(Ⅱ) in sugar and cabbage with satisfactory results.
