采用离子交换法合成了羟基铁铝柱撑膨润土（H-Fe-Al-B），并利用X射线衍射（XRD）和X射线光电子能谱（XPS）对其催化性能进行了分析。以偶氮胭脂红B（AC B）为模型污染物，在紫外光（UV）照射下，考察了不同反应条件下H-Fe-Al-B的光Fenton催化活性。采用Box-Behnken响应面法优化了染料初始浓度、初始pH值和H2 O2浓度3个操作变量对ACB脱色效果的影响。结果表明，羟基铝铁离子成功地插层到膨润土层间，H-Fe-Al-B具有较高的光催化活性。方差分析（ANOVA）表明，所提出的二次模型可用于导航的设计空间。该模型与实验结果基本吻合，相关系数R2、Radj 2和Rpred 2分别为0.9996、0.9991和0.9934。ACB脱色的最佳条件为：染料浓度143.7mg/L，pH 4.2，H2 O2浓度17.7mM。在所建立的模型确定的最佳条件下，预测脱色率为99.6%。在最佳条件下进行了脱色实验，脱色率为99.5%，与预测值基本一致。
Hydroxy-iron–aluminum pillared bentonite (H-Fe–Al-B) was synthesized with ion exchange method, and its catalyst characteristics were analyzed by using X-ray diffraction (XRD) and X-ray photoelectron spectrometry (XPS). The photo-Fenton catalytic activity of H-Fe–Al-B was tested under different reaction condition using azocarmine B (ACB) as model pollutant under ultraviolet light (UV) irradiation. The effects of three operating variables, initial dye concentration, initial pH value and H2O2concentration on the decolorization efficiency of ACB were optimized by response surface methodology (RSM) based on Box–Behnken design. The results showed that hydroxy aluminum iron ions intercalated into the interlayer spaces of bentonite successfully and H-Fe–Al-B had high photocatalytic activity. Analysis of variance (ANOVA) indicated that the proposed quadratic model could be used to navigate the design space. The proposed model was approximately in accordance with the experimental case with correlation coefficients R2, Radj2and Rpred2correlation coefficients of 0.9996, 0.9991 and 0.9934, respectively. The optimum conditions for ACB decolorization were dye concentration of 143.7mg/L, pH of 4.2 and H2O2concentration of 17.7mM, respectively. The predicted decolorization rate under the optimum conditions determined by the proposed model was 99.6%. Confirmatory tests were carried out under the optimum conditions and the decolorization rate of 99.5% was observed, which closely agreed with the predicted value.
