Radiation-modified wool for adsorption of redox metals and potentially for nanoparticles

Original language description

Electron beam irradiated sheep wool with absorbed radiation doses ranging from 0 to 165 kGy showed good adsorption properties toward copper cations. The Cu(ii) being Lewis acid generated several types of complex salts based on carboxylates or cysteinates with ligands available in keratin. Under these conditions, cross-links were formed between the keratin chains. Experimental data obtained from Cu(ii) adsorption using the concentration of 800-5,000 mg/L were tested for fitting to 10 isotherm models. Various compositions and architectures of the Cu(II)-complexes were specified to be responsible for different isotherm model fittings. The copper cation showed adherence to Langmuir, Flory-Huggins, and partially Redlich-Peterson models. The latter clearly distinguished the native wool from the modified ones. Another aim is to investigate the conditions for the adsorption of anti-microbial nanoparticles in addition to the redox-active metals on radiation-modified wool taking into account that the diffusion of nanoparticles into the modified wool is governed by electrostatic interactions.
