Removal of Phosphate Ions from Aqueous Solutions Zn/Al- and Mg/Fe- by Layered Doubled Hydroxides

摘要

The article has investigated processes of sorption removal of phosphate-ions from water media Zn/Al- and Mg/Fe by layered double hydroxides. It was established that sorption properties of these materials are substantially affected by their composition, heat treatment and the pH of the aqueous solution. It is shown that calcined forms of studied sorbents are more effective than their initial carbonate forms.
