Silica monoliths have been used for more than half a century in a wide variety of applications, such as stationary phases for microextraction fibers, capillary columns for chromatography, in the encapsulation of biomolecules for affinity chromatography and for microfluidic or microarray chips and, more recently, and less well known for wastewater treatment. The main objective of this review article is to specifically overview the strategies that use silica monoliths for the removal of chemical pollutants from wastewater effluents or prepared solutions. The discussion of advantages and drawbacks of such strategies will be supported with the main studies carried out so far which have been performed in laboratory environment only. The application and potential research interest in several strategies using composites and biocomposites based silica monoliths as cleaning systems are also discussed.
二氧化硅整体柱在半个多世纪以来被广泛应用于各种领域，如微萃取纤维的固定相、色谱用毛细管柱、生物分子的亲和色谱固定相和微流控或微阵列芯片，最近也开始用于处理废水。本文主要综述了使用二氧化硅整体柱从废水或配制溶液中去除化学污染物的策略。本文仅讨论了迄今为止在实验室环境中进行的主要研究，并对这些策略的优缺点进行了讨论。本文还讨论了几种基于复合材料和生物复合材料的二氧化硅整体柱清洁系统的应用和潜在研究兴趣。
