Crosslinked carboxymethyl cellulose grafted carboxymethyl polyvinyl alcohol (CMC-g-CMPVA) was loaded with modified magnetite iron oxide (FeO) nanoparticles to synthesise a new and easily separable adsorbent for the removal of copper (II) ions from water. The novel adsorbents were characterised by the presence of the functional group, surface morphology, crystallinity and magnetic property. The equilibrium time from the adsorption studies was found to be less than 240min for both film and bead forms while the rate of Cu removal decreased as the initial Cu concentration increased. In addition, CMC-g-CMPVA film loaded with FeO/SiO nanoparticles was the best adsorbent with maximum adsorption capacity of 35.34mg/g and exhibited a reusable potential. The properties exhibited by the new heterogeneous material is a promising adsorbent for the removal and recovery of copper (II) from wastewater.
交联羧甲基纤维素接枝羧甲基聚乙烯醇（CMC-g-CMPVA）负载改性磁铁矿氧化铁（FeO）纳米颗粒，合成了一种新型的、易于分离的吸附剂，用于从水中去除铜（II）离子。新型吸附剂的特征在于存在官能团、表面形态、结晶度和磁性。吸附研究的平衡时间对于薄膜和珠粒形式均小于 240min，而 Cu 去除率随着初始 Cu 浓度的增加而降低。此外，负载 FeO/SiO 纳米颗粒的 CMC-g-CMPVA 薄膜是最好的吸附剂，最大吸附容量为 35.34mg/g，并表现出可重复使用的潜力。新型多相材料所表现出的性能是一种很有前途的吸附剂，可用于从废水中去除和回收铜（II）。
