A method for the purification of aqueous media from ions of heavy metals comprises operation of passing aqueous medium through fine-grained powder, at that total concentration of heavy metals ions in the liquid K is preliminarily determined and simultaneously or alternatively infusion of aqueous medium into the reactor and loading into the reactor of powder or colloid with powder of aluminium oxide and/or aluminium hydroxide (Al2O3 and/or Al(OH)3), which concentration K2 is specified according to the expression of K2=(1/6...1/10)K1 is carried out, carrying out active mixing liquid with powder of aluminium oxide and/or aluminium hydroxide during 30...60 minutes is carried out, and before passing the aqueous medium through the fine-grained powder the liquid is precipitated.
