Recent advances in agricultural waste-based adsorbents for the removal of pollutants in water (2017-2020)

Rapid human activities result in the increasing production of pollutants from both industrial processes and agricultural practices, which negatively impact the environment and human health. Most of chemical pollutants are discharged either intentionally or accidentally via water bodies. Therefore, various pollutants removal techniques have been developed including utilization of agricultural waste as adsorbents. Agricultural waste-based adsorbents are easily prepared, cheap and moderately to highly efficient. A good understanding of agricultural waste-based adsorbents would be beneficial for future research improvements as well as industrial applications. Thus, this review aims at shedding light on recent advancements (from year 2017-2020) in the preparation, characterizations and application of agricultural waste-based adsorbents for removal of different types of chemical pollutants in water and wastewater
