Transfer of electrons between artificial electron donors diphenylcarbazide (DPC) and hydroxylamine (NH2OH) and reaction center of manganese-depleted photosystem 2 (PS2) complexes was studied using the direct electrometrical method. For the first time it was shown that reduction of redox-active amino

In this paper, the reaction mechanism of the system of thallium (III)-copper(II)-ethylenediaminete-traacetate-hydrogen peroxide-diphenylcarbazide has been studied by spectrophotometric method. The experimental results show that the reaction mechanism of the system is based on the replacement of copper(II) by thallium (III)
