• 摘要：在模拟太阳光照射下，4-氯苯酚(4-CP)浓度迅速降低，反应过程对应着产生大量的单线态氧和自由基。金属离子Fe²⁺、Fe³⁺、Al³⁺能够加速这一过程，尤以Fe²⁺、Fe³⁺的影响更明显；在模拟太阳光照射下，向4-CP体系加入的富里酸(FA), 对4-CP浓度降低略起抑制作用，这表明二者之间存在相互作用。但当再加入金属离子Fe²⁺、Fe³⁺、Al

• Abstract：Exposed to simulated sunlight, the concentration of 4-CP reduced rapidly. During this process, a large amount of single oxygen ( 1O₂) and free radicals (ROO·, HO·) were generated. Metal ions, such as Fe²⁺ , Fe³⁺ , and Al³⁺ , especially Fe²⁺ and Fe²⁺ could accelerate this process. Under simulated sunlight, the fulvic acid (FA) added into 4-CP system could restrain the reduction of the 4-CP concentration, indicating that there was an interaction between FA and 4-CP. After metal ions (Fe²⁺ , Fe³⁺ , Al³⁺ ) were added, they could accelerate the reduction of 4-CP concentration.
