Cobalt (II) imprinted chitosan for selective removal of cobalt during nuclear reactor decontamination

Preparation of ion-imprinted mesoporous silica SBA-15 functionalized with triglycine for selective adsorption of Co(II)

“…The Co(II)-IIP showed an obvious advantage over other adsorbents. Compared with those Co(II)-imprinted polymers [23][24][25], Co(II)-IIP prepared in this study presented much higher adsorption capacity and excellent adsorptions rate, though its adsorption equilibrium time was not the shortest. In addition, when it comes to the common functionalized raw materials [40][41][42], higher Q e and good adsorption selectivity also made Co(II)-IIP stand out.…”

“…To overcome this, 2D imprinting method (surface-imprinting technique) has been used [20][21][22], since it provides an alternative way to improve mass transfer and reduce permanent entrapment of ions by imprinting on matrix surfaces. Taking adsorption capacity and equilibrium time into consideration, improvement are still possible for other similar type of adsorbents previously reported [23][24][25].…”

Selective recovery of Pd(II) from extremely acidic solution using ion-imprinted chitosan fiber: Adsorption performance and mechanisms

“…Ion-imprinting technique is a similar approach to prepare molecularly imprinted materials for the target molecules [22,23]. In the conventional method for preparing imprinted polymers, monomer ligands are mixed with template to form their complexes, the complexes are then polymerized with cross-linking agent if needed, and the template is removed from the co-polymers [24].…”

Cadmium Adsorption on Chitosan/Chlorella Biomass Sorbent Prepared by Ionic-Imprinting Technique

“…Tan et al [18], Chen et al [24][25] and Nishad et al [26] prepared Ionic-Imprinted Chitosan to characterize the adsorption of Ni(II), Cu(II), Zn(II), Pb(II) and Co(II) ions using molecular imprinting method introduced by Ekberg and Mosbach. Ionic-imprinting is an inexpensive technique for preparing adsorbent which has a specific template for ion recognition.…”
