| 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 Zn~(2 ) 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 Zn~(2 ).A method of analyzing trace amount of zinc in water after enrichment on SS-MB-TVTA by FAAS was(established),and the Zn~(2 ) concentrations in the water of Xihe(River) and Jialingjiang River were determined. |
| Keywords: | farm by-product straw stalk polyamine straw cellulose sphere zinc |
