Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT The large‐scale application of titanium is limited by its high production costs, as well as its low utilization and recycling rates. Therefore, efficient recovery of titanium scrap offers a viable pathway to reduce its cost. Molten‐salt electrolysis offers a promising route for upcycling titanium scrap, but the conventional method, which ...

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Recovering palladium (Pd) from low‐concentration metallurgical wastewater still poses significant challenges. In this study, triaminoguanidine hydrochloride was used as the key functional site, and three guanidine‐functionalized covalent organic frameworks (GCOFs) were successfully constructed by adjusting the substituents (–H, –OH, and –OCH3)

Gongye shui chuli, 2021 针对沿海工业园区初期雨水含盐量较高，不利于常规生化及难以快速启动的问题，开展改性MBBR填料制备、盐度梯级驯化的研究。研究表明，采用盐度梯级驯化的反应器MBBR稳定运行在第13天完成，比其他挂膜方式快8~10 d。16S rDNA的焦磷酸测序表明R3中球衣菌属高度丰富。因此，盐度梯级驯化是高盐雨水快速启动的有希望的替代方法，使整个系统具有耐冲击、耐盐、启动快等特点，有效降低临港工业园区人工湿地冲击负荷风险。
