“…At higher concentrations the expected concentrating effect of sorption/desorption may be too low to be competitive against other processes such as solvent extraction (especially for valuable metals) or precipitation (for hazardous metals). Many ionexchange and chelating resins have been designed for hydrometallurgy and analytical applications [6][7][8][9]. Alternatively solvent impregnated resins can be used for metal recovery combining the high stability of porous synthetic resin and the extraction properties of solvent extractants [10,11].…”

Synthesis and adsorption characteristics of grafted hydrazinyl amine magnetite-chitosan for Ni(II) and Pb(II) recovery. Abstract:The sorption properties of a functionalized magnetic chitosan sorbent have been investigated for the recovery of Ni(II) and Pb(II) from aqueous solutions. This material was prepared by one-pot co-precipitation of chitosan with formation of magnetic core, followed by a series of grafting step to immobilize hydrazinyl amine derivative at the surface of chitosan layer. The physico-chemical characteristics of this composite material were investigated using FTIR, XRD, thermogravimetric, titration, elemental analyses. In a second step, the sorbent was tested for heavy metal sorption on synthetic solutions through the study of pH effect, sorption isotherms and uptake kinetics, selective sorption (in function of pH), metal desorption and sorbent recycling. Sorption isotherms were modeled using the Sips equation while the uptake kinetics was fitted by the pseudo-second order rate equation. The sorption capacity reached 4.3 mmol Ni g -1 and 2.5 mmol Pb g -1 but the sorbent was more selective to Pb(II) over Ni(II), especially in acidic conditions. The decrease in sorption capacity at the fifth cycle does not exceed 8 %. In the final step of the study, the sorbents were successfully applied for metal recovery from multi-metal synthetic solution and from a contaminated stormwater collected in a local mining area.

Sensors have been extensively used owing to multiple advantages, including exceptional sensing performance, user-friendly operation, fast response, high sensitivity and specificity, portability, and real-time analysis. In recent years, efforts in sensor realm have expanded promptly, and it has already presented a broad range of applications in the fields of medical, pharmaceutical and environmental applications, food safety, and homeland security. In particular, molecularly imprinted polymer based sensors have created a fascinating horizon for surface modification techniques by forming specific recognition cavities for template molecules in the polymeric matrix. This method ensures a broad range of versatility to imprint a variety of biomolecules with different size, three dimensional structure, physical and chemical features. In contrast to complex and time-consuming laboratory surface modification methods, molecular imprinting offers a rapid, sensitive, inexpensive, easy-to-use, and highly selective approaches for sensing, and especially for the applications of diagnosis, screening, and theranostics. Due to its physical and chemical robustness, high stability, low-cost, and reusability features, molecularly imprinted polymer based sensors have become very attractive modalities for such applications with a sensitivity of minute structural changes in the structure of biomolecules. This review aims at discussing the principle of molecular imprinting method, the integration of molecularly imprinted polymers with sensing tools, the recent advances and strategies in molecular imprinting methodologies, their applications in medical, and future outlook on this concept.

This paper describes the preparation of a new type of hybrid material suitable to be used for the amendment of wastewaters laden with Ni ions relying on two purification principles, mechanical and adsorption. The membranes were prepared using as first component copolymers of acrylonitrile with vinyl acetate, acrylic acid or methacrylic acid. The second component of the developed membranes consisted of powdered activated carbon (PAC), of natural or synthetic origin, used in a content of either 4% or 8%. In this way, separation based on porosity is combined with the adsorptive properties of PAC. Hybrid membranes, prepared by phase inversion, were fully characterized by Fourier transform IR (FTIR) spectroscopy, pure water flux analysis, TGA, SEM, Brunauer-Emmett-Teller analysis and XRD. Moreover, water amendment was also investigated using synthetic water bearing heavy metals, in our case nickel, a laboratory electrodialysis set-up being used for this purpose. FTIR revealed that the use of PAC led to several peaks at low wavelength (900-650 cm −1 ). Pure water flux values vary in a fairly wide range, from 0.02 to almost 1.00, depending on the preparation conditions. It can be concluded that the final properties of the developed membranes may be adjusted by changing either the copolymer or the PAC. An additional control is provided by the amount of PAC. The developed membranes were found to achieve an enhanced release of Ni ions, as the percentage of extraction was at least 51%.
