“…The adsorption study using Langmuir isotherm model and maximum monolayer system were recommended for the removal for Pb 2 + , Cd 2 + and Ni 2 + ions, which were found to be 13.7, 18.6 and 13.5 mg/g, respectively against synthesized adsorbent. [134] Zhang et al, synthesized rGO/NiO NCs for the removal of hexavalent chromium Cr (VI) ions from aqueous medium by adsorption model. [135] Results showed that rGO/NiO NCs have strong tendency to adsorb Cr 6 + ion due to the large surface area of composites, the highest adsorption proficiency of Cr 6 + ion on rGO/NiO NCs can reach 198 mg/g, by Langmuir model.…”

Because of the growing population and the industrial revolution, a significant number of toxic materials including heavy metals (HMs) are being released into the environment, posing harm to humans, the environment, and other living organisms. When these HMs find their way into water sources, they cause water pollution and pose a threat to the ecosystem. As a result, there is an imperative need to eliminate these HMs from the water. Numerous techniques are being employed for water purification, but adsorption is the most economical and efficient method. The present article critically discussed the applications of different adsorbents including agricultural wastes, industrial wastes, biochar, chitosan, aerogel‐based adsorbents, geopolymer cement/concrete, carbon‐based nanomaterials (NMs), and polymer‐supported nanocomposites (NCs) for removal of HMs from wastewater. Removal capacity of some of the adsorbents are tabulated. Effects of dose of adsorbent, contact time, pH, temperature, initial ion concentration and ionic strength on the removal of HMs from water have been explored. Various adsorption isotherm and kinetic models have also been discussed, including the modeling using artificial neural networks.

“…Furthermore, the removal e ciency was just decreased by 10% after ve regeneration cycles. Donga C et al [23] coupled graphene oxide on Fe 3 O 4 @SiO 2 -NH 2 to obtain composites for the adsorption of three heavy metal ions on Pb(II), Cd(II) and Ni(II), and showed the absorption capacity followed the order Pb(II) > Cd(II) > Ni(II). From the above studies, it is known that the amino-based magnetic absorbents are chemical stable, reusable and show great application potential of heavy metals removal during the water/wastewater treatment process.…”

Amino-functionalized magnetic particles (Fe3O4@SiO2-NH2) with core-shell structure were synthesized and evaluated for rapid boron removal from aqueous solution. Results showed that the specific surface area of Fe3O4@SiO2-NH2 (165.17 m2⋅g− 1) increased greatly compared to the pure Fe3O4 (49.07 m2⋅g− 1). The adsorption equilibrium was less than 2 h with an adsorption capacity of 29.76 mg⋅g− 1at pH = 6 of 15°C. The quasi second-order kinetic model described well the boron adsorption process and the Freundlich model was more suitable for characterizing the adsorption isotherms. Furthermore, the negative value of Gibbs free energy indicated that the adsorption was spontaneous and an exothermic process. The zeta potential and XPS analysis before and after adsorption revealed that the main adsorption mechanism was the hydrogen bonding formation between the terminal –NH2 groups of the adsorbent and the boric acid. In addition, the adsorbent still maintained a high adsorption performance after five adsorption-desorption cycles, which illustrated that the Fe3O4@SiO2-NH2 may be a potential adsorbent for the environmental boron removal treatment.
