摘要: 以天然粘土矿物累托石为载体、以铁盐作交联剂,利用水溶液插层方法制备了铁/累托石复合物。采用FT-IR和XRD两种表征方法对铁/累托石复合物进行了表征,分析了复合物的结构变化和层间间距变化,并探讨了复合物制备条件以及反应过程中溶液初始浓度、溶液初始pH、复合物投加量和H₂O₂浓度因素对催化降解活性艳蓝的影响。研究表明:铁聚合物插入到累托石的层间结构中,扩大了累托石的层间距;当Na⁺/Fe³⁺比值为0.5,Fe³⁺/累托石比值为10mmol/g,pH为3左右,催化剂用量为0.5g/L时,H₂O₂浓度为100mg/L时,活性艳蓝的去除率达到90%以上。实验表明,铁柱撑累托石/UV/Fenton工艺对活性艳蓝具有良好的降解效果。

Abstract: In this study, by adoption of intercalation solution method, iron/rectorite composite was prepared with natural clay mineral rectorite as the carrier and iron salts as the crosslinking agent. By use of FT-IR and XRD methods, the iron/rectorite composite was characterized and the structural variation and interlayer space change of the composite was analyzed. Furthermore, the conditions for composite preparation and the effects of concentration and pH of the initial solution, the composite dosage and H₂O₂ concentration on the catalytic degradation of reactive brilliant blue were discussed. When ferric polymers were inserted into the layer structure of the rectorite, the interlayer space was expanded. Under the conditions that the ratio of Na⁺ to Fe³⁺ was 0.5, the ratio of Fe³⁺ to rectorite was 10 mmol/g, pH value was about 3, catalytic agent dosage was 0.5 g/L, and H₂O₂ concentration was 100 mg/L, the removal efficiency of reactive brilliant blue was over 90%. Therefore, the experiments indicated that the process of Iron/Rectorite/UV/Fenton had good effects on degradation of reactive brilliant blue.
