摘要： A composition contains a silylated polysaccharide, where the silylated polysaccharide is characterized by: (a) having linked fructose, galactose, anhydrogalactose, or glucose saccharide units provided that glycosidic linkages of glucose are alpha linkages and that the silylated polysaccharide is other than a silylated starch; and (b) on average 1 to 100 mole-percent of the hydroxyl groups on the polysaccharide have been silylated with a silyl group having the structure —SiR3 linked to the polysaccharide through a C—O—Si bond where each R is independently selected from hydrocarbyl radicals having from one to 12 carbon atoms, provided that on average at least one R per polysaccharide has a terminally unsaturated carbon-carbon double bond.

摘要： This invention provides for removal of toxic heavy metal contamination from water using inositol hexakisphosphate. Inositol hexakisphosphate (InsP6 or IP6 aka phytic acid) is a ubiquitous polyphosphorylated carbohydrate with numerous biological and industrial functions including chelation of cations. IP6 hexa-citrate (IP6-citrate) was synthesized and characterized for use as metal chelator in the purification of water. The synthesized IP6-citrate was used to modify the surface of cellulose and the IP6-citrate-modified cellulose subsequently used to remove Pb, Cr and Cd from aqueous solutions. Atomic Absorption Spectrometry and differential pulse anodic stripping Voltammetry were used to test the levels of the heavy metals in water samples before and after the application of IP6-citrate-modified cellulose. The use of IP6-citrate modified cellulose decreased the amount of Cd, Cr and Pb in the water samples by 95-99%. IP6-citrate modified cellulose was superior to IP6-cellulose alone.
