- The study focuses on developing hybrid cryogels that can effectively retain high levels of the antibiotic penicillin G using chitosan and kaolin.
- Three types of chitosan were utilized: commercial chitosan, laboratory-prepared chitosan from chitin, and chitosan extracted from shrimp shells, to assess their stability in water.
- The results indicated that cryogels made from shrimp-derived chitosan showed the best performance in adsorbing penicillin G, confirmed through various characterization techniques and swelling tests.
