TL;DR: A new ion-imprinted amino-functionalized silica gel sorbent was synthesized by the hydrothermal-assisted surface imprinting technique using Cd 2+ as the template, 3-[2-(2-aminoethylamino)ethylaminino]propyl-trimethoxysilane (AAAPTS) as the functional monomer, and epichlorohydrin as the cross-linking agent (IIP-AAAPts/SiO 2 ) for the selective removal of Cd2+ from aqueous solution

TL;DR: In this paper, a matrix separation procedure based on algae C. vulgaris covalently immobilized on silica gel in flow mode has been developed, which shows better reproducibility, improved efficiency of platinum retention on the column (93.3±1.6%), and less laborious and less time consuming.

TL;DR: Deployment of mercapto-silica DGT and Metsorb DGT in seawater spiked with As(III) and As(V) demonstrated the ability of the combined approach to accurately quantify both species in the presence of potential competing ions.
Abstract: A diffusive gradients in thin films (DGT) technique for selectively measuring AsIII utilizes commercially available 3-mercaptopropyl-functionalized silica gel. Deployment of the new technique along...

TL;DR: In this article, the plasmacatalysis and ozonation were combined in a pulsed corona discharge (PCD) reactor to improve the decomposition of aqueous methylene blue.
Abstract: Plasmacatalytic effects of ?-alumina, ?-alumina, and silica gel in a pulsed corona discharge (PCD) reactor on the decomposition of aqueous methylene blue are described. Methylene blue concentration in the effluent was reduced to 23% of the inlet concentration by PCDs in water. Under the same experimental conditions, addition of ?-alumina further reduced it to 8%, ?-alumina to 4%, and silica gel to below the detection limits. PCDs with silica gel were run for >100?h in a continuous flow reactor and methylene blue in the effluent remained below the detection limit. A hybrid system of plasmacatalysis and ozonation is also described. Phenol concentration in the effluent was reduced to 84% of the inlet concentration by PCDs in water. Under the same experimental conditions, addition of either silica gel or ozone further reduced it to around 35%, and simultaneous addition of silica gel and ozone to 14% of inlet concentration. Decolourization of pre-adsorbed methylene blue on silica gel has been demonstrated. Adsorption and stabilization of the chemically active species on silica gel was indicated by experimental evidence. A significant improvement in the rate of decomposition of organic pollutants in water has been realized by hybridizing plasmacatalysis and ozonation in a PCD reactor.
