Photochemical degradation of benzotriazole is investigated in aqueous solution at 25ยกC and pH values varying in the range 3ร11. The quantum yields at di โ erent pH values are evaluated by analysing the kinetics of the reacting system. Reaction kinetics are markedly a โ ected by pH because of its inรue
