Gongye shui chuli, 2003 采用三氯化铁作为混凝剂，通过变化投加量和pH，考察各个分子质量区间的DOC和UV254的变化情况，了解强化混凝去除有机物的效果和机理。增加混凝剂的投加量能有效地促进各分子质量区间的UV254的去除，但对DOC的去除效果较差。三氯化铁对小分子质量的有机物具有很好的去除效果，总去除率的至少50％为去除小分子质量有机物所贡献。降低pH能有效地促进各分子质量区间的DOC和UV254的去除，去除有机物的最佳pH为5．5。在最佳的pH下，小分子质量的有机物得到了最大限度的去除。

Shuitu Baochi Xuebao, 2006 根据2003-2005年曹娥江干流的水质监测资料，对水体中有机物污染进行综合评价，并进行时空变异分析，在此监测阶段，有机物的污染趋于缓解，但仍然属于中度污染。对各断面进行有机物污染综合评价指数的相关性分析和可生化度评价，表明上游水质改善将对下游水质的提高有直接影响；上游2#点有机物污染最为严重；整个干流在1月份有机物污染强度最大，有机物的排放量和流域的水文气象条件是其时空变化的主要因素；下游6#点受工业废水影响较大，水体的生物降解能力相对较低。

Dual‐Layer Solid Electrolyte Interphase Enables Effective Suppression of Lithium Dendrites
Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT The heterogeneous solid electrolyte interphase (SEI) at the Li metal anode often leads to slow and uneven Li+ flux, causing severe Li dendrite growth. Herein, we combine X‐ray photoelectron spectroscopy and cryogenic transmission electron microscopy to demonstrate that a dual‐layer SEI, consisting of an inorganic inner layer and an organic ...

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Although alloy‐based materials present potential for peroxymonosulfate (PMS) activation, metal ion leaching remains severely restricted during the pollution degradation process. Herein, the porous carbon‐supported Fe–Cu alloy derived from industrial copper slag was prepared to remove the organic pollutants from wastewater while inhibiting the ...

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT The healing of diabetic chronic wounds is hindered by multiple pathological barriers, including oxidative stress imbalance induced by hyperglycemia, persistent bacterial infection, and impaired neovascular function. This study developed an F127–HA–BiOCl@CeO2 (FHBC) hydrogel dressing with acoustic responsiveness, achieving tissue repair through

Gongye shui chuli, 2017 研究了竹丝/陶粒混合载体（体积比1∶1）生物膜反应器的水质净化特性和微生物群落特点。结果表明：混合载体生物膜反应器对污水TN、TP和COD的去除率分别为24.7%~89.4%、56.9%~96.8%和70.1%~95.8%，出水NO3--N、NO2--N没有出现积累，具有明显的同步硝化反硝化现象。另外，微生物种群特性研究表明，竹丝表面以有机物降解菌、有机物水解菌、脱氮菌、解磷菌等为优势菌，而陶粒表面以有机物降解菌、有机物水解菌、硝化菌、丝状菌等为优势菌，微生物种群具有良好的强化互补作用。
