The degradation of isoproturon photoinduced by Fe(III) was investigated under both artificial and solar light. The monomeric species Fe(OH)2+ present under the experimental conditions ([Fe(III)] = 3 x 10(-4) M) is the main Fe(III) species responsible for the degradation of isoproturon. The process involves the attack on the pollutant by OH radicals generated by irradiation of Fe(OH)2+. The major primary
研究了在人工和太阳光下,Fe(III)光诱导的异丙隆的降解。在实验条件下([Fe(III)] = 3 x 10(-4)M)存在的单体Fe(OH)2+是负责异丙隆降解的主要Fe(III)物种。该过程涉及Fe(OH)2+辐射产生的OH自由基对污染物的侵蚀。确定了主要的主要照相产品;它们在降解之前会积聚在溶液介质中。在降解过程中,监测溶液对海洋细菌鱼弧菌(Leijmann&Neumann)的毒性。它在反应的早期阶段增加,并且在光产物中,N-甲酰基衍生物似乎是引起毒性增加的主要产物。
