Water resources are getting contaminated globally in a very fast manner due to natural and anthropogenic practices. If this happens with such a pace, it will lead to freshwater scarcity. Therefore, economically feasible, easy to use and technically simple technologies for water treatment must be developed proactively. Adsorption technique, among the other water treatment technologies, might be favorable for the said purpose in terms of techno-economic aspects (cheap, universal, and eco-friendly). However, conventional adsorbents like clay, silica gel, activated carbon, limestone, and activated alumina have certain inherent issues which make their real-world application limited. Therefore, emerging nanoadsorbents may be employed as a replacement of conventional adsorbents in wastewater treatment. Nanoadsorbents have high surface area, porosity, and tunable characteristics. The challenges with the …
