Description
  • The aim of this study was to prepare composite sorbents based on hydrated ferric oxide. Prepared sorbents XAD4-A33 and XAD16-A33 contained iron oxides probably in the form of magnetite, goethite and maghemite. Sorbents showed good chemical stability (at pH 5?9), but not so good mechanical stability. It was found that prepared sorbents can be successfully used for removal of arsenic, beryllium and uranium from aqueous solutions. Removal of beryllium and uranium was less efficient than that of arsenic. Regeneration efficiency of arsenic and beryllium varied between 80 and 90 % and that of uranium was around 50 %.
