Magnetic Biosorbents for Wastewater Treatment

Wastewater treatment is a global concern nowadays. Although there are many methods available for wastewater treatment, the adsorption method has received much more attention from researchers. Major problems for extending the adsorption method to the industry for wastewater treatment are the high cost of cosmetically available adsorbents, their recovery from the medium, and their regeneration and reuse. Magnetic biosorbents could provide easy separation from the treated water and at lower prices compared to other commercially available adsorbents. In terms of characteristics and efficiency in the adsorption of organic and inorganic pollutants, magnetic biosorbents have shown growing promise. If biosorbents and the removed pollutants are not handled and disposed of properly, they can become causes of environmental pollution. There are numerous review papers on wastewater treatment with magnetic adsorbents. However, this paper provides comprehensive information on the synthesis of magnetic nanoparticles, the magnetization of biosorbents, and the application of magnetic biosorbents for wastewater treatment to pave the avenue for new magnetic biosorbents development that can be scaled up from laboratories to the industry.
