Hybrid polysaccharides-based materials
Thursday (29.09.2016) 12:15 - 12:30 Part of:In this work, a set of hybrid materials made of pectin with various secondary polysaccharide additives (inulin, agar-agar, gum arabic, gum gellan, gum tragacanth, gum karaya, guar gum, carob gum, gellan gum and xanthan gum) as potential candidate for biosorption of heavy metals was investigated. Hybrid pectin-based beads were prepared by introduction of pectin and additive mixture into solution containing Ca2+ ions. The various conditions of materials preparation (e.g. temperature of polysaccharide mixing or polysaccharide and Ca2+ concentration) were investigated. The obtained materials were analyzed visually and by scanning electron microscopy as well as Raman and infrared spectroscopy. The results showed the influence of other polysaccharide presence and preparation conditions on structure of obtained biosorbent. The influence of the additive type on hybrid beads swelling ratio was also investigated.
