Kinetics and mechanism of formation of nickel(II)porphyrin and its interaction with DNA in aqueous medium.

Unlabelled: Kinetics between 5,10,15,20-tetrakis(N-methylpyridium-4-yl)porphyrin and Ni species were investigated in aqueous solution at 25 ±1 °C in = 0.10 M (NaNO). Speciation of Ni was done in = 0.
