Abstract
Cu(II) adsorption on cobalt silicate precipitation tube (CSPT) in aqueous medium has been reported. These tubes are porous with negative surface sites having isoelectric point (IEP) at pH 4.4. Cu(II) adsorption data follow Langmuir isotherm. CSPT has high Cu(II) loading capacity, which is a function of both Cu(II) concentration and CSPT weight. Adsorption bond energy obtained from Langmuir isotherm suggests a physisorption process. The adsorption process is endothermic and spontaneous. Adsorption kinetics follows pseudo second order model with activation energy (15.4 KJ mol−1) typical for physisorption process.
