论文摘要
药物和个人护理产品的水污染已成为严重的环境。缓解问题的合理策略涉及吸收材料。特别是，考虑到其高吸附能力和与环境的兼容性，自然粘土的使用是一种有利的替代方法。在目前的工作中，评估了认为是新兴污染物（EC）的磺胺甲恶唑（SMX）的支持，古巴天然粘土（Palygorskite，pal）的疗效。通过紫外线光谱法确定掺入粘土上的SMX量。由红外光谱（IR），X射线衍射（XRD），热重分析（TG/DTG），ZETA电位（ZP），氮吸附测量和透射电子显微镜（TEM）表征所得的复合材料。水溶液中的药物解吸研究表明了掺入过程的可逆性，这表明可能使用PAL纳米粘土作为SMX的有效支持，因此是水去污染的好前景。
Water pollution with pharmaceutical and personal care products has become a serious environmental. A reasonable strategy to mitigate the problem involves absorbent materials. In particular, the use of natural clays is an advantageous alternative considering their high adsorption capacity and compatibility with the environment. In the present work, the efficacy of a Cuban natural clay (palygorskite, Pal) as support of sulfamethoxazole (SMX), an antibiotic considered an emerging contaminant (EC), was evaluated. The amount of SMX incorporated onto clay was determined by UV spectroscopy. The resulting composite material was characterized by infrared spectroscopy (IR), X-ray diffraction (XRD), thermogravimetric analysis (TG/DTG), zeta potential (ZP), nitrogen adsorption measurements and transmission electron microscopy (TEM). The drug desorption studies in aqueous solution indicated the reversibility of the incorporation process, suggesting the potential use of the Pal nanoclay as an effective support of SMX and hence, a good prospect for water decontamination.
