A new analytical method for the determination of gibberellic acid (GA) has been proposed. It is based on the perturbation effect caused by different amounts of GA on the BZ chemical oscillating system: the Mn(II)-catalysed reaction between L-serine, potassium bromate. and malonic acid in acidic medium. The method utilises a linear relationship between the change in the oscillating period and GA concentration...
A new analytical method of the determination of nicotinamide adenine dinucleotide phosphate (NADP) based on its inhibiting effect on the BZ oscillation system has been proposed. BZ mechanism involves Mn(II)-catalyzed reaction between L-serine, potassium bromate and malonic acid in the acidic medium. Determination of NADP was based on the linear relationship between the change in the oscillating period...
