摘要
The influence of oxalate and methanol on the photodegradation behaviour of salicylate under bias was studied measuring the time evolution of the photocurrent and the concentration in solution. In N-2 saturated electrolytes, the presence of the second component produces an enhancement of salicylate degradation, but the degradation of the added photolyte decreases. In the presence Of O-2 or other electron acceptors salicylate photodegradation is faster, and the positive effect of a sacrificial photolyte is minimised. (C) 2002 Elsevier Science B.V.
