Letter to the Editor


A study of fixation of cobalt on the crystalline matrix of titania by co-precipitation was carried out. The tracer level solid-liquid distribution of60Co over preformed hydrous titania showed an appreciable uptake of ∼71%. Macro amounts of Co2+ ions were precipitated along with Ti(IV) hydroxide (pH 8–9) and a maximum loading of ∼29 wt% was observed. The Soxhlet leachabilities of the calcined mixed mass, heated at 1000 °C, were found to be in the order of 10−1 g·m−2·d−1 and the observation of structural changes of the original host matrix of titania revealed the fixation of cobalt in the mineral assemblage of CoTiO3 (rhombohedral) and the rutile form of titania.
