Ulva can overgrow and result in green tides around the world. It forms algal mats on the Wajiro tideland in Japan. The major polysaccharide of Ulva is ulvan, a sulfated glucurono-rhamno-xyloglycan. Ulvan was modified with three 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.
