ABSTRACT:
An adsorbent, which is prepared by subjecting to curing a mixture consisting of (a) one part by weight of at least one member selected from the group consisting of titanium oxide hydrate, zirconium oxide hydrate and tin oxide hydrate and of (b) about 1/10 to 3 parts by weight of an epoxy, unsaturated polyester or polyurethane resin.
The adsorbent can be used as an adsorbent for a great variety of anions and cations and especially as the adsorbent for phosphate ion.
The adsorbent displays also improved chemical resistance, resistant to acids and alkalis, and can be subjected to repeated desorption and regeneration procedures without causing any deterioration of its adsorptive capacity, thus permitting the repeated usage over a long period of time.
