Gongye shui chuli, 2021 研究了不同种类颗粒活性炭（GAC）对湿法冶金MVR废水中特定有机物的去除效果和去除机理。结果表明：相比于Fenton法以及硅胶、硅藻土、膨润土吸附法，颗粒活性炭吸附法对废水中特定有机物的去除率最高，超过90%。GAC对废水中特定有机物的吸附符合Freundlich模型，属于优惠吸附。其中，优适煤制GAC的吸附能力最大，饱和吸附量达到35.98 mg/g（以TOC计），在最佳工况下其对有机物的去除率超过95%。

Boosting Decomposition and Combustion of TKX‐50 and HTPB/TKX‐50 Propellants With NH2‐MIL‐88B(Fe) MOF
Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Dihydroxylammonium 5,5′‐bistetrazole‐1,1′‐diolate (TKX‐50) is a promising energetic material that possesses both exceptional energy density and low sensitivity. Nevertheless, its application is hindered by incomplete pyrolysis during combustion or explosion. Various strategies, including eutectic formation, composite preparation, and catalysis,

Gongye shui chuli, 2014 以带结构正电荷的镁铝层状双金属氢氧化物（Mg-Al-LDH）溶胶为吸附剂系统研究了不同因素对磷吸附去除性能的影响，结果表明：其吸附动力学和吸附等温线分别符合准二级、Elovich速率方程和Langmuir方程，理论饱和吸附量可达55.99～60.90 mg/g。吸附过程的ΔG0为-28.78~-20.67 kJ/mol，吸附机理以静电吸引和化学吸附为主导。无机和有机阴离子会抑制磷在吸附剂上的吸附。200 mg/L的Mg-Al-LDH可以吸附90%以上的溶解性反应磷和84%的总磷 ...

Shuitu Baochi Xuebao, 2007 实验研究了腐殖酸存在下重金属元素镉(Cd2 )在蒙脱石表面的吸附过程,对比研究了两种不同腐殖酸对吸附机理的影响。结果表明,重金属离子在蒙脱石表面的吸附作用受介质pH的影响。加入腐殖酸后吸附产生滞后现象,蒙脱石先吸附腐殖酸,之后转变为腐殖酸和蒙脱石共同吸附Cd2 作用,吸附量较单独吸附过程更大。吸附机理与腐殖酸的投加量和投加方式有关。

Gongye shui chuli, 2021 采用简单溶液法合成了分等级花状磁性氧化镍（NiO）微球，研究了制备的花状磁性NiO微球对水中染料刚果红的吸附效果，并探讨了吸附机理。结果表明，花状磁性NiO微球对刚果红的最大吸附量达155.9 mg/g，吸附机理可归因于带正电荷的吸附剂表面与阴离子染料刚果红之间的静电相互作用。磁性NiO微球能通过磁铁快速从溶液中分离，且对阴离子染料具有良好的选择吸附性能。

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Photocatalytic acetylene (C2H2) semihydrogenation is a green route for ethylene (C2H4) production, yet the activity–selectivity trade‐off caused by imbalanced adsorption/activation of reactants and products remains a core challenge. Herein, we realize precise regulation of Pd oxidation states (Pd0, Pdδ+, and Pd2+) on anatase TiO2 nanocubes via

Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Tin‐based composite oxides typically undergo severe volume variations and exhibit poor intrinsic conductivities despite their high theoretical capacity as promising anode candidates for sodium‐ion batteries. This results in rapid structural degradation and capacity fading upon cycling.
