  • 摘要: 选用经氢氧化钠和纤维素酶预处理的悬铃木果毛（ae-PAF）作为载体，通过一步水热法得到悬铃木果毛基α-FeOOH复合材料（α-FeOOH@ae-PAF），利用SEM、FT-IR和XRD对样品进行表征，详细考察了样品对Cr（Ⅵ）的光催化还原去除性能.实验结果表明，预处理实现了悬铃木果毛表面蜡质及纤维素组分的去除，水热法得到的α-FeOOH@ae-PAF较好地保持了悬铃木果毛的中空管状结构，复合材料表面粗糙；在50 mL浓度为20 mg·L-1且pH=2的Cr（Ⅵ）水溶液中加入10 mg负载量为20%的α-FeOOH@ae-PAF复合材料，40℃下紫外光催化70 min可使Cr（Ⅵ）的去除率达到99.47%.机理分析证实，α-FeOOH@ae-PAF复合材料对Cr（Ⅵ）的高效光催化还原去除是基于α-FeOOH@ae-PAF复合材料对Cr（Ⅵ）和Cr（Ⅲ）吸附性能的差异，由α-FeOOH光催化还原Cr（Ⅵ）所生成的Cr（Ⅲ）能够优势地吸附在复合材料中，实现了Cr（Ⅵ）的光催化还原与Cr（Ⅲ）的吸附转移之间的协同，从而有效提高了体系对水中Cr（Ⅵ）的去除能力.
    Abstract: The Platanus acerifolia fibers (PAF) pretreated by sodium hydroxide and cellulase were employed as biological carriers for α-FeOOH in one-step hydrothermal preparation of α-FeOOH@ae-PAF. The as-prepared samples were characterized with SEM, XRD and FT-IR. And the performance of α-FeOOH@ae-PAF composite in photocatalytic reduction of Cr(Ⅵ) were evaluated in details. The results showed that wax and structural cellulose was successfully eliminated from the natural PAF via alkaline-cellulase modification, and the as-obtained α-FeOOH@ae-PAF inherited the tubular structure of PAF with α-FeOOH rough surface loaded as the result of hydrothermal processing. It was shown that Cr(Ⅵ) removal rate reached as high as 99.47% when 10 mg α-FeOOH@ae-PAF with α-FeOOH content 20% was employed in 50 ml potassium dichromate solution at pH 2 with initial concentration of 20 mg·L-1, when the system was irradiated under UV-light for 70 min at 40℃. As far as the mechanism is concerned, it was found that the differential adsorption capacity for Cr(Ⅵ) and Cr(Ⅲ) of α-FeOOH@ae-PAF contributed to the efficient removal of Cr(Ⅵ) from aqueous solution. The Cr(Ⅲ) transformed from the photocatalytic reduction of Cr(Ⅵ) under UV light was favorably adsorbed by the composite, where the significant synergistic coupling between photocatalytic reduction of Cr(Ⅵ) and the adsorption of Cr(Ⅲ) enhanced the removal of Cr(Ⅵ) with α-FeOOH@ae-PAF.
