Competitive Cation Adsorption on Electron-Irradiated Sheep Wool Changes the Fitting of Adsorption Isotherms for Single-Component Solutions

This work analyses 10 adsorption isotherm models applied to of Cr(III) and Cu(II) from binary solutions on electron-irradiated sheep wool (0-24-100) kGy. The results are compared with fitting the same adsorbates corresponding single solutions. competing cation significantly changes selected isotherms extent that even simultaneous in solution is rare. In case Cr(III), 4 favourable matches were found out 30 cases, while Cu(II), only 2 conformities found. Having coordination number exclusively 6, but up 4, 5, last coordinates more easily ligands provided by keratin, resulting preferential chemisorption. If there still a lack cysteic acid interact also, this adsorbed physically, too. amount increasing absorbed dose energy improves chemisorption as well. It can be summarized during competitive adsorption, binds both physisorption chemisorption, depending wool.
