Abstract

pH-dependent efficiency of singlet oxygen (1O2) generation by fulvic acids (FAs) from different sources was estimated by time-resolved luminescence technique. All FAs turn up the highest quantum yields of 1O2 for neutral and alkali solutions [ϕ532(1O2)] = (0.3•2.5)í10•2] and 3•5-fold decrease in ϕ532(1O2) for acidic solutions. Potential of FA ChangSheng (the best 1O2 generating agent among investigated FAs) in relation to photodegradation of non-UVA-absorbing herbicide Amitrole (3-amino-1,2,4-triazole) was demonstrated.
