| 摘 要： | 研究了不同条件下锰矿砂对４种取代酚的光氧化作用。结果表明，ｐＨ＝３．１０±０．０４时，苯酚、对氯苯酚、对氨基酚及对苯二酚均能被锰矿砂光催化氧化。低ｐＨ值，适当的苯酚初始浓度及适当的锰矿砂浓度有利于锰矿砂对取代酚的氧化；离子强度和溶解氧浓度不影响反应速度。对其可能的机理及取代基效应进行了讨论。

| Abstract: | The photooxidation of four substituted phenols by manganese ore particles were studied.The results indicated that oxidation of phenol,p\|chlorophenol,p\|aminophenol and hydroquinone by manganese ore particles was enhanced by illumination.Low pH,proper initial concentration and proper manganese ore particle concentration were favorable to oxidation of the substituted phenols.No effects of ionic strength or dissolved oxygen concentration were found.The possible mechanisms and substituted effects were discussed. |

| Keywords: | photooxidation natural minerals manganese ore particles substituted phenols |
