The conductivity and the adsorption capacity of surfactant modified hydrous titanium oxide gels
Electrical conductivity measurements as well as adsorption investigations show that the electrical conductivity and the amount of copper ions adsorbed from aqueous solutions pass through maxima with increasing concentration of surfactant in surfactant-doped titanium gels. Electron spin resonance measurements reveal that the intensity of the signal assigned to adsorbed O2− depends on the surfactant content, while Fourier transform-infrared measurements provide evidence for peaks which disappear after adsorption. It is reasonable to assume that the groups responsible for these peaks represent adsorption sites.
