Effect of excess charge of cadmium sulfide colloid particles on interphase rate of electron transfer

Kinetics of photodecolorization relaxation of aqueous solutions containing CdS colloid with particle size approx 50 A, L-cysteine as electron donor and oxygen as electron acceptor, has been studied. Photodecolorization relaxation kinetics reflects of nonequilibrium electron transfer from CdS particles to oxygen molecules in solution. The regularities defined are explained proceeding from the assumption on the effect of excess electrons charge on potential of colloid particles double layer, i.e. on apparent activation energy of electron interphase transfer
