Abstract:
Cobalt(Ⅱ) in NaOH(a.q.) can catalyze the decolorizing reaction resulting from the oxidation of dibromohydoxylphenylfluorone(DBH-PF) by H2O2(a.q.). A new catalytic spectrophotometry for determining trace Cobalt(Ⅱ) was obtained. The method has been used to determine trace Cobalt(Ⅱ) in Vitamin B12 samples. The sensitivity of this method is higher than the references, and the selectivity of the method is better than the references too.
