Abstract

Oily wastewater poses great risks to the ecosystem, human health and living organisms. Therefore, the development and study of sorbents using various activation techniques to remove oils from water resources is of interest to the scientific community. Here, we present a review on the use of sorbents made from agricultural waste to remove oils and hydrocarbons from aqueous media. After modification, it was found that activated carbon made from agricultural waste improves the performance of the adsorption process. The presentation also includes a comprehensive analysis of the application of isothermal models, kinetic models and thermodynamic parameters. The selectivity of the sorbent is the main focus of the adsorption kinetics and isothermal models. The process of adsorption and other parameters affecting adsorption such as contact time, solution temperature, solution pH and amount of sorbent are also studied. The use of agricultural waste as sorbents is economically and environmentally beneficial for the removal of oily pollutants.
