Adsorption properties of ionic species on cross-linked chitosans modified with catechol and salicylic acid moieties.
Catechol-type chitosan resin and salicylic acid-type chitosan resin were easily synthesized for use in estimating the adsorption behavior of 34 elements at pH 1 - 7 in aquatic media. The catechol-type chitosan resin could adsorb Cu(II) at pH 3 - 7, In(III) at pH 4 - 6, Pb(II) and lanthanoids at pH 5 - 7, and U(VI) at pH 4 - 7 more effectively than the salicylic acid-type chitosan resin and the ...
متن کاملFabrication of chemically cross-linked porous gelatin matrices.
PURPOSE The aim of this study was to chemically cross-link gelatin, by reacting its free amino groups with an aliphatic diisocyanate. METHODS To produce hydrogels with controllable properties, the number of reacting amino groups was carefully determined. Porosity was introduced into the gelatin-based hydrogels through the lyophilization process. Porous and non-porous matrices were characteriz...
متن کاملCompetitive adsorption of dye metanil yellow and RB15 in acid solutions on chemically cross-linked chitosan beads.
One kind of adsorbent with a high adsorption capacity for anionic dyes was prepared using ionically and chemically cross-linked chitosan beads. A batch system was applied to study the adsorption behavior of one acid dye (MY, metanil yellow) and one reactive dye (RB15, reactive blue 15) in aqueous solutions by the cross-linked chitosan beads. The adsorption capacities was 3.56 mmol g(-1) (1334 m...
متن کاملAdsorption Mechanism for Aniline on the Hypercross-Linked Fiber
A type of novel hypercross-linked fiber adsorbent was obtained by sulfonation and cross-linking reaction of polypropylene fiber grafted styrene-divinylbenzene. The aim of the fiber sulfonation and cross-linking method was to prepare rigid three dimensional networks in the entire fiber and change the ion exchange capacity of fiber. The hypercross-linked fiber adsorbent possesses a principall...
متن کاملPhotoelectrochemical Measurement of Phthalic Acid Adsorption on Porous TiO2 Film Electrodes
A new adsorption measurement method based on photoelectrochemical oxidation principle has been developed. The method can be used to directly quantify the amount of adsorbates at TiO2 electrode surface in a sensitive and accurate manner. The adsorption of phthalic acid on TiO2 was studied as a test case. The relationship between the amount of the adsorbate at TiO2 surface and the concentration o...
