| 摘 要： | 本文合成了一系列不同氧化度的酸性和碱性水钠锰矿,以对苯二酚作为腐殖质形成的前驱物,分析水钠锰矿矿物类型和亚结构变化对对苯二酚腐殖化程度的影响。取得的主要结果有:水钠锰矿的矿物类型和亚结构(锰氧化度、八面体空位、H+、Mn4+和Mn3+含量)对对苯二酚的腐殖化程度具有重要的影响,且矿物类型的影响大于同种矿物不同亚结构产生的影响。酸性水钠锰矿比碱性水钠锰矿含有更多的H+,导致酸性水钠锰矿比碱性水钠锰矿具有更高的氧化容量,反应达到平衡后,对苯二酚腐殖化程度更高。因此,水钠锰矿物中H+含量对对苯二酚腐殖化程度的影响要大于矿物中Mn4+和Mn3+含量的影响。同种类型水钠锰矿氧化度越高,得电子量将越多,氧化容量越大,反应达到平衡后,对苯二酚腐殖化程度越高。
