Abstract

Sustainable chemistry and green chemistry are now integral components of environmentally-friendly materials science, pollution adsorption studies, and particularly research on oil pollutants. Mesoporous materials currently play a significant role in water purification, and extensive research is being conducted to analyze and characterize these materials' pore size distribution, from laboratory experiments to industrial applications. The Barrett-Joyner-Halenda (BJH) method is one of the most widely used approaches for this purpose. In this study, we investigated pumice-based sorbents modified with charcoal and bentonite. The results revealed that these sorbents have mesoporous characteristics, and their pore size distribution is significantly correlated with the actual sample's oil contaminant removal efficiency in an aqueous environment. These findings provide valuable insights into the design and optimization of mesoporous sorbents for practical applications. Moreover, the BJH analysis serves as an accurate criterion for oil contaminant adsorption in such systems. This study marks an important step towards the development of cost-effective, eco-friendly methods for oil pollutant purification from water using green mesoporous materials.
