  • 摘要: 通过稀硫酸活化凹凸棒黏土，再与高黏土混合，制备颗粒黏土吸附剂。通过X射线衍射（XRD）、场发射扫描电镜（FE-SEM）、N2吸附-脱附等温线和傅里叶红外光谱（FT-IR）对吸附剂粉末进行表征测试。结果表明：凹凸棒黏土由水硅锰钙石（Kittatinnyite）、坡缕石（Palygorskite）和石英（Quratz）3种成分组成；黏土表面呈杂乱堆积的纤维状和针棒状，比表面积高达126.43 m2·g-1；动力学吸附数据符合准二级动力学模型和离子内扩散模型，热力学吸附数据符合Langmuir吸附模型，在323 K时，最大吸附量达到153.85 mg·g-1；颗粒吸附剂对印染废水中亚甲基蓝具有较好的吸附性能，是一种具有发展前景的新型吸附材料。
    Abstract: In this study, attapulgite clay was acidized using dilute sulfuric acid and mixed with high clay to prepare a granular adsorbent. A powder of the adsorbent sample was characterized by X-ray diffraction (XRD), field-emission scanning electron microscopy (FE-SEM), nitrogen adsorption-desorption isotherm analysis, and Fourier transform infrared spectroscopy (FT-IR). The results show that attapulgite clay is composed of kittatinnyite, palygorskite, and quartz. The surface morphology of the clay is fibrous and needle-shaped, and the specific surface area of the powdered sample is 126.43 m2·g-1. The adsorption of methylene blue by the clay is described by pseudo-second-order kinetic and intra-particle diffusion models. The Langmuir adsorption model provides the best correlation with the experimental data, with a maximum monolayer uptake capacity of 153.85 mg·g-1 at 323 K. The granular adsorbent offers a superior adsorption capacity for methylene blue dyes and has potential commercial value.
