An apparatus for purifying blood has a blood compartment and a clearance compartment separated by a semi-permeable membrane. The apparatus includes a device containing a cation exchange resin charged with metal ions whose phosphates are insoluble in water. Metal salts of iron, aluminum, zirconium, lanthanum, thorium and tin are deposited on a cation exchange material and the charged cation exchange resin is contacted with dialysis liquid. The process of treating blood with the dialysis liquid is also contemplated.

Dialysis with ion exchange extraction of phosphates

Ferric ions are removed from a concentrated aqueous zinc solution having a pH value in the range of about 0 to about 1.3, by contacting the zinc solution with a cation exchange chelate resin containing aminocarboxylic acid and/or iminodicarboxylic acid groups.
