  • 摘要: 研究了常温常压下颗粒状活性炭(GAC)与过一硫酸盐(PMS)联合体系降解水中金橙Ⅱ时GAC可循环利用的问题.实验发现,本体系中GAC可以重复使用,循环4次后GAC的催化活性只降低了4.6%.说明该体系具有较好的GAC再生能力,氧化剂的用量越大再生能力越强.在GAC催化PMS降解金橙Ⅱ的过程中,PMS可能会氧化GAC的表面,使得GAC的催化能力得以加强.同时发现该体系中仅是GAC的催化能力得到很好的再生,而吸附能力并没有得到再生.当GAC几乎失去吸附能力时,催化能力仍几乎能保持不变.当PMS与金橙Ⅱ的物质的量之比为20:1时,连续流实验进行10 d,GAC的催化活性仍未减弱,GAC的使用寿命较长.该体系具有很好的实际应用潜力.
    Abstract: In this paper, the reuse of granular activated carbon (GAC) in the GAC and peroxymomosulfate (PMS) combined system to degrade azo dye Acid Orange 7 (AO7) was studied. It was discovered that GAC could be reused. After four cycles, the GAC catalytic capability was reduced by only 4.6%. The catalytic capability increased as the dosage of PMS increased. During the process of AO7 degradation, GAC surface was oxidized by PMS and the catalytic ability of GAC was enhanced. It was found that only the catalytic ability was regenerated, but the sorption capability was not. Even when GAC lost most of its sorption ability, its catalytic ability remained at the same level as before. After 10 days continuous operation, GAC had no obvious deactivation. This system would be significant for practical applications.
