Abstract

Environmental pollutants that are dangerous to human health have been present at much higher amounts throughout the past few decades. The goal of the study is to create artificial and organic adsorbents for the removal of dangerous heavy metals, pesticides, mycotoxins, antibiotics, and other developing contaminants. However, selectivity and sustainability prospects are lacking in the application of promising adsorbents in remediation. In the context of sustainability, the current study attempts to provide a critical debate on the adsorption potential of synthetic and natural adsorbents. The fundamental sorption processes and recipes for the synthetic adsorbents are described. Here, a practical examination of innovative synthetic adsorbents like ferrate is explained using designed nanoparticles and green chemistry concepts.
