首途

Analysis based on the experimental results demonstrated the plausible reaction mechanism is that vit C first converts Cu(superscript 2+) to its reduced state and vit C becomes vit C radical itself, thereby stimulating the formation of peroxyl and alkoxyl radicals, and bimolecular reaction of peroxyl radicals results in (superscript 1)O2 production in the systems studied.

根据实验观察的结果，分析了这一体系中(上标 1)O2形成的可能途迳，认为首先是维生素C将Cu(上标 2+)转变为还原态，而自身失去一个电子转变为维生素C自由基，从而刺激了过氧自由基和烷氧自由基的形成，过氧自由基的双分子反应很可能就是体系内(上标 1)O2产生的反应机制。
