Gongye shui chuli, 2018 进行了强化混凝法去除腈纶废水中COD的研究。结果表明，铁碳微电解预氧化可提高混凝处理效果。通过对分子质量分布、Zeta电位及核磁共振波谱的测定发现，铁碳微电解的氧化作用可导致大分子有机物降解为小分子有机物，小分子有机物矿化，因此提高了分子质量>50 ku和<3 ku的有机物去除率；微电解产生的Fe2+有电性中和作用，使Zeta电位降低，强化混凝效果；微电解的氧化作用主要破坏酯类和醚类结构。

Dimensional Assembly Engineering of Ce‐MOF Interfaces for Selective Recognition of Phytic Acid
Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Selective molecular recognition is central to chemical sensing yet discriminating structurally similar molecules at complex interfaces remains challenging. Traditional strategies based on tuning size, charge, or binding‐site chemistry often suffer from limited flexibility.

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)

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Lung cancer remains the leading cause of cancer‐related deaths worldwide, yet immune checkpoint blockade (ICB) is often compromised by an immunosuppressive tumor microenvironment (TME) with acidosis, hypoxia, and poor T cell infiltration. Here, we develop a TME‐responsive nanoplatform (MgH2@Lip/PD‐L1) that couples hydrogen gas therapy with PD ...
