Two-Dimensional Ti₃C₂T_x MXene Nanosheets for Efficient Copper Removal from Water

ACS Sustainable Chemistry & Engineering, Journal Year: 2017, Volume and Issue: 5(12), P. 11481 - 11488

Published: Oct. 27, 2017

The performance of two-dimensional (2D) Ti3C2Tx MXene nanosheets in the adsorption and copper removal from aqueous media was investigated. Delaminated (DL)-Ti3C2Tx exhibited excellent Cu ability, because their large specific surface area, hydrophilicity, unique functional properties. Scanning electron microscopy coupled with energy-dispersive spectroscopy (SEM–EDS), transmission (TEM), Brunauer–Emmett–Teller (BET), X-ray photoelectron (XPS), diffraction (XRD) analyses were performed to analyze structural changes its interaction ions. Oxygenated moieties layered structure facilitated reductive Cu2+ forming Cu2O CuO species. DL-Ti3C2Tx a higher faster uptake, compared multilayer (ML)-Ti3C2Tx. maximum experimental capacity (Qexp,max) 78.45 mg g–1, 80% total content metal ions adsorbed within 1 min. A pseudo-second-order kinetic model Freundlich isotherm accurately describe equilibrium time uptake onto adsorbent material, respectively. Thermodynamic analysis revealed that process endothermic. (Qe) 2.7 times than commercially available activated carbon. present results illustrate promising potential 2D for toxic metals water.

Fe(II) Redox Chemistry in the Environment

Chemical Reviews, Journal Year: 2021, Volume and Issue: 121(13), P. 8161 - 8233

Published: June 18, 2021

Iron (Fe) is the fourth most abundant element in earth's crust and plays important roles both biological chemical processes. The redox reactivity of various Fe(II) forms has gained increasing attention over recent decades areas (bio) geochemistry, environmental chemistry engineering, material sciences. goal this paper to review these advances current state knowledge environment. Specifically, comprehensive focuses on four types species including aqueous Fe(II), complexed with ligands, minerals bearing structural sorbed mineral oxide surfaces. formation pathways, factors governing reactivity, insights into potential mechanisms, comparison, characterization techniques are discussed reference breakthroughs field where possible. We also cover applications zerovalent iron, microbial processes, biogeochemical cycling carbon nutrients, their abiotic oxidation related processes natural engineered systems.

Nanoscale, Journal Year: 2020, Volume and Issue: 12(8), P. 4790 - 4815

Published: Jan. 1, 2020

The shortage of water resources and increasingly serious pollution have driven the development high-efficiency treatment technology. Among a variety technologies, adsorption is widely used in environmental remediation. As class typical adsorbents, metal oxides been developed for long time continued to attract widespread attention, since they unique physicochemical properties, including abundant surface active sites, high chemical stability, adjustable shape size. In this review, basic principles process will be first elucidated, affecting factors, evaluation index, mechanisms, common kinetic isotherm models. Then, properties several oxides, key parameters performance such as particle/pore size, morphology, functionalization modification, supports calcination temperature discussed, well their application removal various inorganic organic contaminants. addition, desorption recycling spent adsorbent are summarized. Finally, future oxide based adsorbents also discussed.
