Preparation and Absorption Properties of Polyamine Straw Cellulose Spheres
Abstract:
Natural cellulose in farm by-products such as bagasse or straw stalk was choosen as the material.After epoxy straw cellulose was treated with polyamines,polyamine straw cellulose spheres(SS-MB-TVTA,SS-MB-TEPA,SS-MB-TMDA) with good hydrodynamic and mechanical performance were prepared.They can adsorb heavy metals ions from water(for example,the static adsorption capacity of three kinds of polyamine straw cellulose spheres for Zn2+ were 17.58,4.04,and 6.54 mg/g,respectively).SS-MB-TVTA with better hydrodynamic property was chosen to prepare separation columns,which was applied to enrich and separate Zn2+.A method of analyzing trace amount of zinc in water after enrichment on SS-MB-TVTA by FAAS was established,and the Zn2+ concentrations in the water of Xihe River and Jialingjiang River were determined.
