“…El procedimiento NTS incluyó extracción con mezclas de solventes orgánicos, limpieza por cromatografía de permeación en gel de alta resolución de dos pasos, fraccionamiento, cromatografía de gases (GC), análisis HRMS en ionización electrónica (EI) e ionización química de iones negativos por captura de electrones (ECNI) (Rebryk & Haglund, 2022). Las ciclodextrinas (CD) son adsorbentes de contaminantes, son económicos y respetuosos con el medio ambiente, además son relativamente fáciles de usar y se han descrito muchas técnicas para su funcionalización; podrían usarse para eliminar diferentes contaminantes mediante el uso de diversos métodos, por ejemplo, adsorción/ extracción, lavado de suelos y procesos electrocinéticos/catalíticos (Wacławek et al, 2022). Las estructuras orgánicas covalentes (COF) son materiales valiosos construidos mediante fuertes interacciones covalentes entre monómeros bloqueados.…”

Persistent organic pollutants (POPs) represent a significant environmental problem due to their toxicity, with a high capacity to persist in the environment, resistance to conventional degradation methods, the ability to accumulate in living organisms and their magnification in food chains or food. In this review article, the impacts on health and environmental components are examined. Strategies and measures for control, mitigation and/or minimization of POPs are also addressed. Agricultural and industrial activities, inadequate final disposal of solid waste and lack of wastewater treatment are identified as the main sources of POP emissions. In addition, innovative and promising technologies are analyzed, such as nanotechnology, bioremediation, rhizoremediation, biochar, chromatography techniques, ultrasound, among others, for the adequate treatment of POPs. The review highlights both the advantages and limitations of these technologies, pointing out areas that still require developments to achieve effective treatments. More economical and ecological alternatives are also mentioned to counteract the impacts of POPs.

“…[9] However, the adsorption efficiency of AC is dictated by PFAS chain length; shorter PFAS are not easily adsorbed like long-chain PFAS because they are highly soluble in water. [10] AC can be combined with other substances, such as polymers, to form composite materials with enhanced adsorption properties. For instance, Ramos et al modified the surface of GAC with a positively charged polymer (poly diallylmethylammonium chloride).…”

PFAS, or per‐ and polyfluoroalkyl substances, have received considerable attention due to their persistence in the environment and potential health risks. To address this problem, adsorption has emerged as an effective method for removing PFAS compounds from water. This review provides a comprehensive analysis of various adsorbents used for PFAS removal, including activated carbon, ion exchange resins, clay, and emerging materials such as covalent and metal‐organic framework adsorbents. The effectiveness of these adsorbents in removing PFAS compounds is discussed, along with the factors influencing their adsorption, such as pH, competitive matters, and temperature.This article is protected by copyright.
