Abstract

Per- and Polyfluoroalkyl substances (PFAS) are a group of synthetic compounds, which have been commonly used in both household and industrial settings. Because of their widespread use, resistance to breaking down, and potential harmful effects to the environment and human health, PFAS compounds have been classified as emerging contaminants. Similar to activated carbon, biochars as a carbon rich material can be used as an adsorbent to remove PFAS contaminants. This study aims to generate novel designer biochars as cost-effective adsorbents to efficiently capture PFAS from aqueous solutions. The designer biochars were produced from biomass pretreated with calcium, magnesium, and aluminum-based substances. The enhanced sorption mechanisms for PFAS by the designer biochar were characterized. The effects of pyrolysis temperature and mixed ratios on PFAS removal by the designer biochars were evaluated. The most cost-effective and efficient designer biochar was selected to comprehensively investigate its sorption kinetics and isotherms to PFAS.
