Recent Developments in the Adsorption of Heavy Metal Ions from Aqueous Solutions Using Various Nanomaterials

Materials, Journal Year: 2024, Volume and Issue: 17(21), P. 5141 - 5141

Published: Oct. 22, 2024

Water pollution is caused by heavy metals, minerals, and dyes. It has become a global environmental problem. There are numerous methods for removing different types of pollutants from wastewater. Adsorption viewed as the most promising financially viable option. Nanostructured materials used effective adsorption techniques to extract metal ions Many nanomaterials, such zero-valent oxides, carbon magnetic nanocomposites, adsorbents. Magnetic nanocomposites adsorbents have properties abundant active functional groups, unique nanomaterials endow them with better than nonmagnetic (classic adsorbents). Nonmagnetic adsorbents) typically limitations limited capacity, adsorbent recovery, poor selective adsorption, secondary treatment. easy recover, strong selectivity high safe economical, always been hotspot research. A large amount data collected in this review, which based on an extensive study synthesis, characterization, capacity elimination wastewater their separation water. The effects several experimental parameters ion removal, including contact duration, temperature, dose, pH, starting concentration, ionic strength, also investigated. In addition, variety illustrations describe various kinetics isotherm models, providing insight into process.

Preparation of K-F Zeolite from Koh-Excited Synthetic Powders and Efficient Selective Adsorption of Sr2+ in Cs+/Sr2+ Solutions

Published: Jan. 1, 2025

In this study, K-F zeolite (Linde F) was prepared using a geopolymer technique (non-hydrothermal) with synthetic powder. The composition, morphology, and performance of were analyzed characterized XRD, SEM/EDS, FT-IR, XPS, ICP, AAS, DFT. removal rates Cs+ Sr2+ could be controlled below 2.5% above 98% by changing the dosage to 2.5 g/L or adjusting K+/Na+ concentration in solution 200/1500 mg/L, respectively. Using 8 g/L, seawater are 2.03% 93.34% respectively, achieving efficient separation Cs+/Sr2+. integration experimental characterization DFT calculations revealed that is through ion exchange mechanism, while physical adsorption. Under conditions 0.3 pH=6, adsorption kinetics isotherms for comply pseudo-second-order kinetic model Langmuir isotherm (Qm=256.36 mg/g, T=298 K), It shows has great application prospect removing from nuclear waste water

Selective Recovery of Rare Earth Elements from Mine Wastewater Using the Magnetic Zeolite Prepared by Rare Earth Tailings

Published: Jan. 1, 2025

The effective enrichment and recovery of rare earth elements (REEs) from wastewater holds significant practical value for both the sustainable utilization REEs restoration ecological environments. In this study, magnetic zeolite was successfully synthesized by using tailings (RET) as raw material, with addition Fe3O4 to introduce a phase. Th exhibits high crystallinity, excellent thermal stability, substantial specific surface area 483.8 m2/g, rapid adsorption kinetics. maximum capacities La3+ Ce3+ in aqueous solutions were determined be 123.2 mg/g 99.9 mg/g, respectively, efficiencies remaining above 70% 80% after six cycles.Magnetic effectively employed recover real acid mine wastewater, recoveries exceeding 90%, distribution coefficients (Kd) 2681.7 mL/g 5321.8 mL/g, demonstrating notable selectivity. Moreover, can easily separated an external field, addressing challenges typically associated conventional zeolite. Overall, through technology, loss environmental pollution caused renewable energy technologies are addressed, thus presenting strategy simultaneous remediation.
