Fe/Mn-MOF-driven rapid arsenic decontamination: Mechanistic elucidation of adsorption processes and performance optimization
Arsenic pollution in water poses a serious threat to the natural environment and human society, making the development of efficient adsorbents for arsenic removal an urgent necessity. Therefore, Fe/Mn bimetallic MOF materials with different ratios were simply prepared using a hydrothermal method. Among them, Fe/Mn-MOF (1:1) exhibited excellent adsorption effects for As (III) and As (V), with maximum theoretical adsorption capacities of 344.14 mg/g and 228.79 mg/g, respectively, outperforming the original MIL-88 A material. Single-factor experiments showed that Fe/Mn-MOF (1:1) could efficiently remove As (III) and As (V) within 30 min. The pH value and interfering ion concentration affected the adsorption behavior of As (III), but had little effect on the adsorption behavior of As (V). After five regeneration cycles, Fe/Mn-MOF (1:1) still maintained excellent arsenic removal efficiency. The adsorption mechanism was explored through characterization methods and the results indicated a strong coordination interaction (M-O-As) between arsenic and Fe/Mn-MOF (1:1), while Fe and Mn facilitated the conversion of As (III) to As (V).
期刊介绍：
The Journal of Water Process Engineering aims to publish refereed, high-quality research papers with significant novelty and impact in all areas of the engineering of water and wastewater processing . Papers on advanced and novel treatment processes and technologies are particularly welcome. The Journal considers papers in areas such as nanotechnology and biotechnology applications in water, novel oxidation and separation processes, membrane processes (except those for desalination) , catalytic processes for the removal of water contaminants, sustainable processes, water reuse and recycling, water use and wastewater minimization, integrated/hybrid technology, process modeling of water treatment and novel treatment processes. Submissions on the subject of adsorbents, including standard measurements of adsorption kinetics and equilibrium will only be considered if there is a genuine case for novelty and contribution, for example highly novel, sustainable adsorbents and their use: papers on activated carbon-type materials derived from natural matter, or surfactant-modified clays and related minerals, would not fulfil this criterion. The Journal particularly welcomes contributions involving environmentally, economically and socially sustainable technology for water treatment, including those which are energy-efficient, with minimal or no chemical consumption, and capable of water recycling and reuse that minimizes the direct disposal of wastewater to the aquatic environment. Papers that describe novel ideas for solving issues related to water quality and availability are also welcome, as are those that show the transfer of techniques from other disciplines. The Journal will consider papers dealing with processes for various water matrices including drinking water (except desalination), domestic, urban and industrial wastewaters, in addition to their residues. It is expected that the journal will be of particular relevance to chemical and process engineers working in the field. The Journal welcomes Full Text papers, Short Communications, State-of-the-Art Reviews and Letters to Editors and Case Studies
