Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Aqueous zinc‐ion batteries are plagued by anode challenges such as dendrite growth and corrosion, which stem from intrinsic surface heterogeneity. Although constructing a homogeneous interfacial layer is a promising strategy, conventional electrolyte additives often suffer from incomplete or unstable coverage.

Gongye shui chuli, 2023 针对电镀废水中因含有硫脲类物质而造成生物处理系统硝化受抑制的问题，以广东省某电镀废水厂为例，通过硫脲对硝化的抑制原理、铜离子与硫脲对硝化抑制与恢复特性试验及电镀废水生物处理系统长期项目运行数据分析，得出电镀废水生物处理系统运行中次氯酸钠投加、铜离子浓度与硫脲相互作用是导致硝化抑制与恢复的原因。铜离子与硫脲形成配合物后不再对氨氧化菌产生抑制，而次氯酸钠可解除硫脲与铜离子的配合态，使硫脲对氨氧化菌重新获得抑制性。小试研究发现0.2、0.5、1.0 mg/L的硫脲对氨氧化菌分别造成59.5%、82.5 ...

Rare Metals, Volume 43, Issue 8, Page 3702-3712, August 2024.Graphical abstract AbstractThe highly reversible insertion/extraction of large‐radius K+ into electrode materials remains a tough goal, especially for conversion‐type materials. Herein, we design a current collector‐integrated electrode (N–CoSe/CoSe2–C@Cu) as an advanced anode for potassium‐ion battery (PIBs).

Gongye shui chuli, 2012 将离子交换膜分离装置与化学反应器结合构成离子交换膜化学反应器,并对含铜离子废水进行处理,研究结果表明:化学反应器能将从受体池进入化学反应器的铜离子沉淀下来,而含有高浓度补偿离子钾离子的溶液则全部回流到受体池,节约了药剂及水的成本。该技术具有能耗低、操作简单、无二次污染等优点。
