Preparation of core–shell ion imprinted nanoparticles via photoinitiated polymerization at ambient temperature for dynamic removal of cobalt in aqueous solution

摘要: In this work, novel core–shell ion imprinted polymers were firstly synthesized by photoinitiated polymerization (P-IIPs) for the selective separation of Co(II) in aqueous solution. contrast to thermal polymerization, exhibits faster initiation rate, only a quarter former, and can be performed at room temperature. Subsequently, extensive characterizations using FT-IR, SEM, TEM, XRD, TGA. Adsorption isotherm kinetics studies carried out batch adsorption experiments. Furthermore, removal from solution was investigated different conditions P-IIPs as adsorbent fixed-bed column parameters discussed optimized. The data well fitted Thomas model, offering some model process design. Compared with non-imprinted polymers, displayed remarkable selectivity toward Co(II). Moreover, possessed excellent desorption performance regeneration property efficiency up 94.1%. enabled extraction successfully sediment samples satisfactory recovery. above mentioned results indicate that are promising high-performance, low-energy environmentally friendly adsorbents effectively removing
