2，4-二氯苯氧基乙酸的Fenton型(Fe3++H2 O2)氧化在近紫外光下的光增强是由于Fe(III)敏化的几个光化学反应所致。研究了Fe3+/H2 O2/UV体系在废物处理中的潜在应用。2，4-D的第一个∼的40%的环和羧基碳的脱氯和转化为CO2的主要原因是羟基自由基(OH)。)反应
The photoenhancement of Fenton-type (Fe 3+ +H 2 O 2 ) oxidation of 2,4-dichlorophenoxyacetic acid in the near-UV is due to several Fe(III)-sensitized photochemical reactions. Fe 3+ /H 2 O 2 /UV systems were studied for potential use in waste treatment. Dechlorination and conversion of the first ∼40% of ring and carboxy carbon of 2,4-D to CO 2 are due mostly to hydroxyl radical (OH . ) reactions
