Contribution to Understanding Iodine Sorption …
An experimental study on the iodine sorption mechanism onto mixed solid alumina cement and calcium compounds was carried out. The solids were prepared by mixing the alumina cement with Ca(OH) 2 and/or CaSO 4 ·2H 2 O. Batch experiments were performed for iodine sorption onto the solid and iodine desorption from the solid that was obtained after a sorption experiment.
