We introduce a new adsorbent, bimetallic chitosan particle (BCP) that is successfully synthesized and applied to remove the orange II dye from wastewater. The effects of pH, BCP quantity, and contact time are initially verified on the basis of the percentage of orange II removed from the wastewater. Experimental data reveal that the Cu/Mg bimetal and chitosan have a synergistic effect on the ad...
The removal of copper from aqueous solution by Amberjet 1500H, Amberjet 1300H and Amberlite IRC86 ion exchange resins is described. The Amberjet 1500H shows a remarkable increase in sorption capacity for copper compared to other adsorbents. The adsorption process shows maximum removal of copper in pure aqueous solution for an initial copper concentration of 5.98 mmol/L. The metal ions adsorptio...

Electron beam irradiated sheep wool dosed (0–410) kGy showing good adsorption properties was tested for Cr(III) and Co(II) of higher concentrations. Fitting to ten isotherm models examined as follows: Langmuir, Freundlich, Dubinin-Radushkevich, Temkin, Flory-Huggins, Halsey, Harkins-Jura, Jovanovic, Elovich Redlich-Peterson. Both cations being Lewis acids generate complex salts, such carboxylat...
