  • What mechanisms control wastewater treatment using mineral adsorbents?
  • Research studies (listed in Supplementary Table 4) showed that physical adsorption, chemical adsorption, and ion exchange are the most common mechanisms controlling wastewater treatment using mineral adsorbents.
  • Are industrial wastes cost-effective adsorbents for removing PTEs from wastewater?
  • Industrial wastes are believed to be cost-effective adsorbents for removing PTEs from wastewater. Usually, they require no treatment to increase their adsorption capacity [ 116 ], but it is possible to improve their adsorption capacity through physical and chemical modifications or by treating them with other elements.
  • Why is adsorption important in wastewater management?
  • Wastewater management remains the utmost challenge toward environmental sustainability and public health. Among numerous techniques developed for the treatment of wastewater, adsorption has been found to be one of the most effective and versatile methods due to its simplicity, efficiency, and the broad range of pollutants it can remove.
  • How adsorbents are used in wastewater treatment?
  • The most promising technique is the use of different materials as adsorbents that have a higher efficacy in treating wastewater, with a minimal production of secondary pollutants. Biosorption is a key process that is highly efficient and cost-effective. This method majorly uses the adsorption process/mechanism for toxicant removal from wastewater.
