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.

A Green Anodic Electrolysis Strategy for Recovering Copper and Selenium From Cuprous Selenide
Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Selenium, a rare strategic metal, is essential for advanced technologies and biological systems. Cuprous selenide (Cu2Se), a selenium‐rich compound found in copper anode slime and a promising thermoelectric material, holds great potential for recovery.

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).

Shuitu Baochi Xuebao, 2006 棕壤对铜的吸附特性以及土壤条件对吸附的影响进行了研究，结果表明，棕壤对铜的吸附随溶液中铜的平衡浓度增加而增加，但在高浓度时增幅渐缓，与处于相同地区的褐土相比棕壤的吸附相对较弱，其吸附可用Langmiur、Frundlich、Temkin及米氏方程进行描述。土壤酸度增强，棕壤对铜的吸附降低，用H^＋浓度对Frundlich方程进行修饰，能更好地描述铜的吸附状况。此外，离子强度、陪伴离子对吸附都有影响，随离子强度增加及高价陪伴离子比例的上升吸附减弱。

Gongye shui chuli, 2007 线路板生产废水是一种含有高浓度金属离子和CODCr等污染物的难处理废水。采用预处理+二级混凝沉淀工艺并用硅藻精土处理剂作混凝剂对线路板废水进行处理,运行结果表明,在进水CODCr、铜离子质量浓度平均分别为303.00、43.59mg/L时,出水CODCr为66.03mg/L,铜离子为0.03mg/L,均达到排放标准。用硅藻精土处理剂对线路板废水进行二级混凝沉淀处理不仅对废水中铜离子具有非常显著和高效的去除效果,且出水水质稳定,优于常规处理工艺出水,运行成本为1.64元/t。
