Description
Adsorption of Th(IV) by Luffa Cylindrica sponges after controlled surface oxidation by nitric acid has been investigated by batch-type experiments as a function of various physicochemical parameters (e.g. adsorption capacity, pH, ionic strength, mass of the adsorbent, temperature and contact time). Fitting of the experimental results reveal that even under strong acidic conditions the relative sorption is above 70% and the maximum adsorption capacity of the biochar fibres for Th(IV) is qmax= 70 g·kg-1, at pH 3. In addition, experimental results related to the effect of ionic strength on the adsorption efficiency and corresponding IR studies clearly indicate that adsorption occurs through the formation of inner-sphere complexes.
