Abstract

There are several techniques for removing contaminants from water and wastewater. Meanwhile, surface adsorption is one of the simplest, most effective and most economical methods for water and wastewater treatment. This article reviews recent research on the removal of various contaminants with a variety of adsorbents from water and wastewater. In this study, a large number of adsorbents such as natural adsorbents, agricultural waste, industrial by-products, biomass, various types of nanosorbents including carbon-based nanomaterials, new metal-based nanomaterials, metal oxide-based nanosorbents, nanomaterials With spinel ferrite base, nanocomposites, geopolymer cement and dendritic polymers to remove various contaminants from water and wastewater have been discussed. This article also tries to point out the advantages and disadvantages of each adsorbent and the future research needs in the field of water and wastewater treatment by adsorbents.this research showed that there are various aspects related to adsorbents which require detailed investigation.attempts are needed to optimize the process parameters.
