“…The sorption isotherms obtained were tested with the Langmuir and Freundlich isotherm equations. The Langmuir isotherm model assume that the adsorption of molecules occurs at specific homogeneous sites of the adsorbent and, once a molecule occupies a site, no additional adsorption can occur there (monolayer coverage) [35]. The Freundlich isotherm model assumes the molecules undergoes adsorption onto the heterogeneous surface of adsorbent.…”

This work investigated cadmium ions biosorption on Fish scales (FS) of Sardina pilchardus. Different relevant parameters such as initial pH in the range 2.14 -7.76, initial cadmium concentration from 35 to 150 mg L -1 , and biosorbent dose in the range 50 -300 mg L -1 , were examined. The effect of these parameters on the cadmium removal was analyzed and optimized using full factorial design methodology and the analysis of variance. The kinetics were modelized for pseudo-second order and pseudo-first order models. Results showed that the pseudo-second order kinetic gave the best fit for equilibrium data. The biosorption isotherms were investigated for Freundlich and Langmuir models. Langmuir isotherm model gave the best fit and led to a maximum biosorption capacity of Cd(II) on FS of 52.08 mg g -1 . The results indicated that FS of was effective in the removal of cadmium ions. Optimum Cd(II) removal of 88.2% was calculated for pH 3, 75 mg L -1 of Cd(II) and 250 mg L -1 of FS. Monte Carlo simulation was used as relatively greener pathway to study the biosorption behavior of Cd(II) ions onto FS. It showed that the interaction Cd(II)hydroxyapatite was more favored than Cd(II)collagen.

“…Water:ethanol or water:methanol ratio varies according to the solubility of the template. The most commonly used cross-linker is tetraethoxysilane (TEOS) [ 166 , 168 , 169 , 170 ]. Figure 9 represents a hybrid organic-inorganic printing procedure.…”

“…The silica-based materials allow the use of high temperature for template removal from the polymer network, a step that has always been challenging in MIP synthesis, and they provide products of high thermal and mechanical stability with longer lifetime [ 170 , 172 ]. L. Wang et al, (2019) [ 173 ] established a comparative study between three different molecularly imprinted polymers for gossypol, which showed that MIP prepared by bulk polymerization had a high adsorption capacity (564 mg/g) but MIS showed faster adsorption kinetics (40 min) [ 168 ].…”

This review aims to pin out the importance of developing a technique for rapid detection of antioxidants, based on molecular imprinting techniques. It covers three major areas that have made great progress over the years in the field of research, namely: antioxidants characterization, molecular imprinting and electrochemistry, alone or combined. It also reveals the importance of bringing these three areas together for a good evaluation of antioxidants in a simple or complex medium, based on selectivity and specificity. Although numerous studies have associated antioxidants with molecular imprinting, or antioxidants with electrochemistry, but even electrochemistry with molecular imprinting to valorize different compounds, the growing prominence of antioxidants in the food, medical, and paramedical sectors deserves to combine the three areas, which may lead to innovative industrial applications with satisfactory results for both manufacturers and consumers.

“…The most used MIM are acrylate-based polymers. We already demonstrated that sol–gel molecularly imprinted polymers were more specific than their equivalent acrylate-based polymers [ 7 ]. For this reason, only molecularly imprinted silica was prepared in this study.…”

Molecularly imprinted sol–gel silica (MIS) coupled to a microwave sensor was designed and used to detect phenylacetaldehyde (PAA), a chemical tracer of wine oxidation. The developed method is fast, cheap and could replace the classical chromatographic methods, which require a tedious sample preparation and are expensive. To reach our objective, five MIS and their control non-imprinted silica (NIS) were synthesized and their extraction capacity toward PAA was studied in hydro alcoholic medium. The selected polymers, based on this first step, were subjected to a selectivity study in the presence of PAA and three other competing molecules. The best polymer was integrated in a microwave sensor and was used to assess PAA in red wine. The developed sensor was able to detect PAA at the µg·L−1 level, which is below the off-flavour threshold.
