✦ Synopsis

Photochemical degradation of benzotriazole is investigated in aqueous solution at 25Β‘C and pH values varying in the range 3È11. The quantum yields at di †erent pH values are evaluated by analysing the kinetics of the reacting system. Reaction kinetics are markedly a †ected by pH because of its inΓ‘uence upon benzotriazole dissociation. A mathematical method that takes into account the presence of intermediates and of the pH has been developed.
