Abstract:
The preparation and properties of a new adsorbent cross-linked agar beads entrapped attapulgite clay (CAA) are reported in detail. Medicinal attapulgite clay made in China was encapsulated with agar, shaped in organic solvent, and cross-linked by epichlorohydrin . The products withstood autoclaving at 121 ℃ for half an hour with no breakage, and had a good selective adsorption ability for some model compounds and medicaments such as methylene blue and phenothiazine drugs. Preliminary investigations and SEM photographs indicate that the CAA as an adsorbent is relatively hemocompatible for hemoperfusion.
