Development of Coupled Electrochemical Systems for Metal Resource Recovery From Aqueous Metal‐Organic Complexes

open access: yesRare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT The past decade has witnessed a burgeoning demand of metals for global industrial development and infrastructure. Meanwhile, the depletion of mineral resources and the environmental damage caused by wastewater discharges pose significant threats to both economic and ecological sustainability. Fortunately, metal‐containing wastewaters also hold

膜分离技术在工业废水处理中的应用

open access: yesGongye shui chuli, 1986
在工业废水中几乎都包括了不同浓度的有用成份,这些成份有的具有较高的经济价值应当加以回收,有的具有不同的毒性,会造成水体环境的严重污染,则应根据工业废水排放标准加以处理。所以,对工业废水的处理既希望对废水能进行有效的净化,又希望对废水中有价值的物质进行回收,而膜分离法在这方面显示出明显的优越性。目前,反渗透和超过滤的膜分离技术已在废水处理中得到了广泛的应用。本文就电镀废水、含油废水,化纤及印染废水、电泳漆装饰废水、造纸废水和放射性废水等利用膜分离的情况进行介绍。

Surface Sulfate Modification Promoted Excitons Extraction of BiOBr Nanosheets for Efficient 1O2 Photosynthesis and Chlorophenols Dechlorination

open access: yesRare Metals, Volume 45, Issue 2, February 2026.
ABSTRACT Photocatalytic molecular oxygen (O2) activation provides a sustainable approach to produce singlet oxygen (1O2) for organic contaminants detoxification. However, the charge carriers‐involved pathway usually suffers from unsatisfactory 1O2 production efficiency owing to energy loss caused by photogenerated hole‐mediated superoxide species (•O2−

Prioritized Lithium Extraction From Spent Lithium‐Ion Batteries via Low‐Temperature Chlorination Mediated by Seawater‐Derived Chlorides

open access: yesRare Metals, Volume 45, Issue 2, February 2026.
ABSTRACT Chlorination roasting has emerged as a promising pyrometallurgical strategy for the selective recovery of lithium from spent lithium‐ion batteries (LIBs). In this study, a natural roasting agent, seawater‐derived chlorides, was employed to selectively extract lithium from spent LiNi0.5Co0.2Mn0.3O2 (NCM523) cathode. MgCl2·6H2O, a main component

火电厂的废水处理及其发展趋势

open access: yesGongye shui chuli, 1986
工业废水排放造成水体污染和水资源的大量消耗,是目前国内外普遍关注的问题。而火电厂每天使用大量的水,并在运行中产生相当数量的废水,是一个水体的严重污染源和用水大户。火电厂的废水主要包括:冲灰(渣)水、化学废水、煤场排水、冷却塔排污、锅炉排污、除尘器清洗废水、空气预热器清洗废水和其它废水。废水的排放方式有连续排放和间歇排放两种,连续排放是正常运行中的排放水,它的水质相对比较稳定,间歇排放设备启动和检修时的排水, 其水量大小和水质变化都很大。

Band Edge Reorganization via Symmetry Constraints in Covalent Bonding Heterojunctions Boosts Photocatalytic Metronidazole Degradation

open access: yesRare Metals, Volume 45, Issue 2, February 2026.
ABSTRACT The covalent bonds at heterojunction interfaces enable more efficient charge carrier separation than traditional weakly coupled heterojunctions, with enhanced photocatalytic performance for organic wastewater purification. The interfacial covalent bonds drive energy band reorganization, rendering the conventional independent band edge ...

Achieving Transboundary Water Security Through Water Innovations: A Framework and Cases

open access: yesWorld Water Policy, Volume 12, Issue 1, February 2026.
ABSTRACT Alternative sources of freshwater, provided by various innovations, have long been available to countries facing acute water stress. We hypothesize that avoiding and/or resolving conflict with neighbors—caused by the uncertainty of continued access to shared surface water and groundwater sources—is another driver of innovation adoption ...

A Dual Closed‐Loop Process to Recycle High Nickel Cathode of Spent Lithium‐Ion Batteries via Deep Eutectic Solvents: Computational Screening and Experimental Validation

open access: yesRare Metals, Volume 45, Issue 1, January 2026.
ABSTRACT Deep eutectic solvents (DESs) have displayed a significant potential in green recycling of spent lithium‐ion batteries (LIBs) cathode materials. In this study, we proposed a computational screening strategy based on the binding energy and hydrogen bonding performance via density functional theory and molecular dynamic calculation, achieving a ...

人工湿地废水处理系统的生物学基础研究进展

open access: yes, 1996
主要阐述了人工湿地废水处理系统中生物学基础的研究进展。至今,对作为湿地生产者的水生植物研究较多,水生植物除直接吸收利用废水中的营养物质、吸附和富集重金属外,还起输送氧气至根区、形成根区多种微环境和维持湿地水力传输的作用;而对作为湿地分解者的微生物(包括细菌、放线菌、真菌、原生动物和藻类)的研究较少,湿地微生物的代谢活动是废水中有机物质降解的基础机制。应加强人工湿地中生物学基础、特别是湿地中微生物的结构与功能的研究 ...
