Abstract
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.
Claims16
In a method for the preparation of a cation exchanger charged with metal ions adapted for controlling the phosphate level in blood by oral administration, the steps which comprise charging a cation exchanger with from 10% to 100% alkali metal ions before or after it is charged with ions of iron (III), tin, lanthanum, aluminum or zirconium.
A phosphate sorbent for oral administration capable of controlling the phosphate level in blood comprising an organic cation exchanger charged with ferric ions in a pharmaceutically acceptable carrier.
