Аннотация:The possibility of purifying aqueous solutions from dyes with the use of layered double magnesium–aluminum oxides is studied. Using stamp ink as an example, it has been demonstrated that the complete recovery of dye from the solution is attained at the time of contact between the liquid (L) and solid (S) phases of 120 min and S : L = 1 : 25. The same complete recovery of dye from the aqueous solution is attained upon repeated contact between the stamp-ink solution and the solid phase of the sorbent containing stamp ink. No desorption of dye from the sorbent into the aqueous solution is observed after 120 min of contact.
