Sodium alginate and chitosan are added to a CaCl2 solution to prepare calcium-alginate-chitosan and calciumalginategels. After dehydration through stoving, two types of adsorbent particles are obtained. The adsorption processof the particles obtained for low concentrations of Sr2+ satisfies a second-order kinetic equation and the Freundlich adsorptionmodel. The thermodynamic behaviors of the particles indicate that adsorption occurs via a spontaneous physical process. XPS pattern analysis is used to demonstrate the adsorption of Sr2+ by calcium alginate and chitosan. By buildingan interaction model of the molecules of chitosan and alginate with Ca2+ and Sr2+ to calculate energy parameters, Fukuiindex, Mulliken charge, and Mulliken population, adsorption of Sr2+ on the molecular chains of chitosan as well as theboundary of calcium-alginate-chitosan is observed to show weak stability; by contrast, adsorption between molecularchains is high.
