In this article, a study was presented on the adsorption activity of a new nanocomposite particle , which was synthesized by combining [Cu(HL)₂]₂H₂[P₂Mo₅O]·10H₂O () (HL = 2-acetylpyridine semicarbazone) and Fe₃O₄ nanoparticles. Transmission electron microscopy and X-ray powder diffraction analyses revealed that possessed high crystallinity with an average particle size of 19.1 nm. The adsorption activity of the as-prepared was investigated by photometrically monitoring the removal of methylene blue, rhodamine B, safranine T, gentian violet, fuchsin basic, and methyl orange from aqueous solutions. Significantly, we could easily separate from the reaction media by applying an external magnet. Furthermore, the recycling performance was observed using methylene blue, revealing the recyclability and high stability of . It was shown that is a promising candidate material for adsorbing cationic dyes in aqueous media.
在本文中，展示了一项关于新型纳米复合颗粒吸附活性的研究，该颗粒通过将[Cu(HL)₂]₂H₂[P₂Mo₅O]·10H₂O（）（HL = 2-乙酰基吡啶缩氨基脲）与Fe₃O₄纳米颗粒结合合成。透射电子显微镜和X射线粉末衍射分析表明，其具有高结晶度，平均粒径为19.1nm。通过光度监测从水溶液中去除亚甲基蓝、罗丹明B、番红花红T、龙胆紫、碱性品红和甲基橙，研究了所制备的该颗粒的吸附活性。值得注意的是，通过施加外部磁场，我们可以轻松地将该颗粒与反应介质分离。此外，使用亚甲基蓝观察了其循环性能，揭示了该颗粒的可回收性和高稳定性。结果表明，该颗粒是用于吸附水性介质中阳离子染料的有前景的候选材料。
