| Research Abstract |
I converted acidic polysaccharides (ulvan) from green tide-forming alga Ulva pertusa into soft hydrogel materials. In addition to ulvan, the hydrogels also contained alginate in a polyion complex with chitosan. We also found that both ulvan-chitosan gel and alginate-chitosan gel were able to remove urea and heavy metals from aqueous solution.
Ulvan was modified with 3 diisocyanate derivatives to yield urethane foam and its ability to remove Cu(II) ions from an aqueous solution was investigated. Notably, the foam could remove up to 72.7% of Cu(II) ions.
