天然坡缕石对新污染物吸附-解吸循环后的稳定性
Stability of a natural palygorskite after a cycle of adsorption-desorption of an emerging pollutant
摘要：
在本文中，我们评估的结构稳定性的天然古巴粘土（吸附剂的有机污染物）后的吸附-解吸过程。研究中的粘土是坡缕石，磺胺甲恶唑是新出现的污染物。采用X射线衍射、衰减全反射红外光谱和Zeta电位等方法对吸附前后的材料进行了表征。基于材料的完整性，证明了作为污染物吸附剂的潜在性及其在吸附-解吸循环中的可能再利用。
英文摘要：
In this paper, we evaluate the structural stability of a natural Cuban clay (an adsorbent of organic pollutants) after an adsorption-desorption process. The clay under study was palygorskite, and sulfamethoxazole was the emerging contaminant. The materials were characterized by X-ray diffraction, attenuated total reflection infrared spectroscopy and zeta potential before and after the sulfamethoxazole adsorption-desorption processes. Based on the material integrity, the potentiality of Pal as pollutant adsorbent and its possible reuse in adsorption-desorption cycles was demonstrated.
