Converting date seed biomass to absorbing hydrogel

Converting biomass to value added products have been attracted a lot of focused in recent years. In this paper a facile approach for using date seed powder without de liginification was introduced to convert date seed biomass to absorbing polymer. The biomass of date seed as a source of polysaccharides is immersed in emulsions of acrylic microgels with different chemical structure. Different polymer latex based on acrylic Acid (AA), sodium acrylate (SA) acrylamide (AM) and 2-Acrylamide -2-Methyl Propane Sulfonic Acid (AMPS) was prepared through inverse emulsion polymerization. The effect of latex type on modification of date seed to absorbing polymer was investigated. The best modification of date seed to absorbing hydrogel was obtained with poly(AA-SA-AM-AMPS).The modified date seed with this latex have water absorbency up to 48.83g/g while water absorbency of unmodified date seed is only 0.2 g/g.
