Construction of a novel ion imprinted film to remove low concentration Cu2+ from aqueous solution

N-alkylation briefly constructs tunable multifunctional sensor materials: Multianalyte detection and reversible adsorption

“…At present, there are many types of materials used for adsorption. Especially, recycling these adsorption materials can save the cost of materials to a large extent and is conducive to environmental protection (Liu et al, 2020(Liu et al, , 2021Huang et al, 2021a;Wang et al, 2020b;Chen et al, 2020a), especially for multifunctional material (Chen et al, 2021). Using Cu 2+ as an example, the cyclic adsorption application of SPBIs was investigated (Figure S40).…”

A recoverable magnetic surface ion-imprinted polymer based on graphene oxide for fast and selective adsorption of Ni(ii) from aqueous solution: experimental and DFT calculations

“…To further study the adsorption mechanism of the adsorbent, the data were fitted by the Langmuir isotherm model, Freundlich isotherm model and Scatchard model. The linear expressions of models were as follows eqn (9), eqn (10), eqn (11) and eqn (12). 42,43 Langmuir isotherm equations:…”

“…Adsorption has been widely employed among these technologies due to its advantages of ease of operation, low cost, and high efficiency. 9 However, traditional adsorbents lack the ability to separate specific metal ions with sufficient selectivity, which restricts their application in metal recovery.…”

Selective removal and recovery of Ni(ii) using a sulfonic acid-based magnetic rattle-type ion-imprinted polymer: adsorption performance and mechanisms

“…The relevant thermodynamic parameters were calculated to clarify the thermodynamic mechanism of the adsorption process. The Gibbs free energy (DG), enthalpy (DH) and entropy (DS) were evaluated as follows eqn (10) and (11). 4 DG = −RT ln(1000K c ) (10)…”

“…[7][8][9][10] Among these methods, adsorption has been widely used because of its merits of facile operation, costeffectiveness and high efficiency. 11 However, traditional adsorbents lack the selectivity separation for specic metal ions, which limits their application in specic metal recovery.…”
