Emerging novel polymeric adsorbents for removing dyes from wastewater: A comprehensive review and comparison with other adsorbents

Dye molecules are one of the most hazardous compounds for human and animal health and the excess intake of these materials can create toxic impacts. Several studies show the practicality of the adsorption process for dye uptake from wastewaters. In recent years, various adsorbents were used to be efficient in this process. Among all, polymeric adsorbents demonstrate great applicability in different environmental conditions and attract many researchers to work on them, although there is not enough reliable and precise information regarding these adsorbents. This study aims to investigate some influential parameters such as their type, physical properties, experimental conditions, their capacity, and further modeling along with a comparison with non-polymeric adsorbents. The influence of the main factors of adsorption capacity was studied and the dominant mecha-nism is explained extensively.

Automated summary

Dye molecules are highly hazardous compounds for human and animal health, with excess intake potentially creating toxic impacts. The adsorption process is practical for dye removal from wastewater, with polymeric adsorbents showing efficiency in various environmental conditions and attracting researchers, despite lacking reliable information. Studying influential parameters, such as type, properties, and capacity of adsorbents, alongside modeling and comparison with non-polymeric adsorbents, provides insight into the dominant mechanism of adsorption capacity.
