Spectrophotometric Study of the Interaction Between Pyridoxine with Some Transition Metal Ions in Non-aqeuos Media

Vitamin B6, also called pyridoxine, is one of 8 B vitamins. All B vitamins help the body convert food (carbohydrates) into fuel (glucose), which is used to produce energy.These B vitamins, often referred to as B-complex vitamins, also help the body metabolize fats and protein. B-complex vitamins are needed for healthy skin, hair, eyes and liver. They also help the nervous system function properly [1]. Electronic spectral behavior and complex formation reaction for pyridoxine in various non-aqueous media for understanding of these media function has been investigated. In this research, the complex formation reaction of C8H12ClNO3 pyridoxine ligand with nitrate salts of cadmium, nickel, zinc, mercury, cobalt and copper in binary solvents of acetonitrile and dimethyl sulfoxide has been investigated ]2[. According to the experiments conducted in this study, the best non-aqueous solvent was dimethyl sulfoxide, because the pyridoxine is dissolved in the presence of this solvent and reacted to the complex formation reaction. The trmodynamic of complex formation reaction was studied spectrophotometrically and the formation of both 1:1 and 1:2 complexes with Pyridoxine and cations was stablished. The complex formation constants Kf were determined by computer fitting of the absorbance – mole ratio data. The presence of isobestic points confirmed theformation of simple complex formation. By decreasing the proportions of the dimethyl sulfoxide, the formation of the complexes increase, which correlates with the solventreceptor.
