摘要
The photosensitized oxidation of parathion-ethyl (PTE) pesticide in the aqueous solution of anthracene substituted dextran (DXA) was investigated. The phototransformation of PTE was found to be significantly enhanced in the presence of DXA. The suggested mechanisms of reactions involve photoinduced electron transfer process as a primary photophysical step. DXA polymer plays a role of environmentally friendly photosensitizer since after the reaction it undergoes decomposition. (c) 2004 Elsevier B.V. All rights reserved.
