Sustainable and green novel sorbent-based immobilization of PFAS and their enhanced adsorption to treat environmental contamination

The persistent environmental contamination resulting from per- and polyfluoroalkyl substances (PFAS) presents substantial challenges to both environment and public health, thereby underscoring the persistent necessity for sustainable remediation approaches. The removal of PFAS from contaminated water using sorbent materials, particularly sustainable and green materials, is a critical area of research due to their inherent biodegradability, biocompatibility, and eco-friendly properties. This review explores recent progress in sustainable and eco-friendly strategies aimed at PFAS immobilization through the creation of novel sorbent materials. By emphasizing the incorporation of biodegradable and nontoxic constituents, we elucidated the improved adsorption efficacy of engineered sorbents for the effective sequestering of PFAS compounds. A thorough examination of various batch experiments indicated that these novel sorbents exhibit enhanced PFAS removal efficiency compared to conventional remediation techniques. Moreover, we highlight the challenges that remain despite the promising attributes of sustainable and eco-friendly sorbents for PFAS removal and deliberate on prospective opportunities for their extensive utilization in the ongoing efforts to combat PFAS pollution.
