ABSTRACT:
The present invention discloses a phosphate adsorbent comprising an MgO-TiO.sub.2 complex as an active ingredient and a phosphate adsorbent having said complex deposited on active carbons. In the preferred embodiments of the present invention, the MgO/TiO.sub.2 molar ratio in the complex is in the range of 99.99/0.01 to 80/20, the specific surface area of the adsorbent as measured by BET method is in the range of 50 to 700 m.sup.2 /g. and the absorbent shows a crystal diffraction pattern of MgO in powder X-ray diffractometry. The phosphate adsorbent according to the present invention is useful as an antihyperphosphoremial agent, an adsorbent for hemoperfusion and a therapeutical agent for renal diseases.
