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−

生物炭吸附水中污染物的性能、机理和环境风险

open access: yesGongye shui chuli, 2023
生物炭因其比表面积大、表面官能团丰富和孔隙结构发达等优势在废水处理领域具有广阔的应用前景。未改性生物炭对污染物的吸附性能不理想,可通过改性方式提升其吸附性能。总结了生物炭的制备条件(热解温度、升温速率、保温时间)和改性方法(酸/碱改性、老化改性、有机物改性、纳米材料改性、蒸汽改性和球磨改性)对生物炭吸附去除污染物的影响。概括了生物炭对重金属离子和有机污染物的吸附机理,其中生物炭吸附去除重金属离子的相互作用包括静电吸附、离子交换、物理吸附、表面络合、共沉淀等,而吸附去除有机污染物的相互作用包括孔隙填充 ...

Contribution of microcosm experiments to conservation science

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
Abstract Microcosms, or miniature experimental systems, have been used to develop models and theories in ecology. However, their contribution to conservation science is unclear. We explored the application, design, and impact of microcosms in conservation science from 469 systematically identified articles published from 1986 to 2023.

生物过滤处理微污染原水的性能研究

open access: yesGongye shui chuli, 2004
以生物过滤作为微污染水处理的末级处理工艺,可使有机污染物和浊度的去除在同一滤层内实现,是一种经济、有效的生物处理方法。作者通过模型试验,深入探讨了生物过滤对微污染水中有机物、氨氮、浊度等的去除效果。试验结果表明:生物过滤能够有效地去除微污染水中的有机物、氨氮等物质,同时能够获得与常规过滤一样低的出水浊度。

Mitigating light pollution impacts on arthropods based on light‐emitting diode properties

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
Abstract Light pollution from artificial light at night (ALAN) is a significant environmental problem with far‐reaching consequences for ecological systems. Recent innovations in light‐emitting diode (LED) technology may offer sustainable outdoor lighting solutions, but scientific evidence is lacking. We investigated the effects of various LED lighting

Evolution of research on global amphibian declines

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
Abstract In the late 1980s, the scientific community became aware of severe, enigmatic amphibian population declines. These declines triggered a wave of research focused on quantifying their extent and identifying key drivers. We used text‐analysis techniques, including topic modeling and geoparsing, to examine the evolution of research focused on ...

磁化改性吸附剂去除废水中污染物的研究进展

open access: yesGongye shui chuli, 2022
近年来随着农业和工业领域的高速发展,纺织、化学制造、农副产品加工、医疗等行业产生大量废水。这些废水中含有染料、重金属、持久性有机污染物、药物及个人护理品等多种污染物,排入水环境后造成自然水体的严重污染。生物吸附法具有高吸附量、低成本、环境友好等特点,常用于废水中各类污染物的吸附去除。然而,生物吸附法在净化废水过程中普遍存在吸附剂回收难、回收不彻底的难题,导致水环境发生再次污染。磁化改性技术可使磁性吸附剂与水溶液实现快速分离,解决生物吸附剂吸附后回收困难的问题。综述了磁性天然生物材料 ...
