Investigation of catalytic reaction with spectrofluorimetric method.
Numerous derivatives of nicotinic acid hydrazids are suitable for sensitive fluorescence determination of metal ions. The reaction proceeds upon ultraviolet illumination in the presence of an oxidizing agent and catalyst forming a fluorescent product. Therefore, the catalyst metal ion can be quantitatively determined by fluorescence methods. We have studied the reaction of nicotinic acid (di-pyridin-2-yl-methylene)-hydrazide (NADPMH), catalyzed by Mn(II)ion, and determined the optimal parameters of metal ion method.
