Synthesis and study of biosorbent properties

We propose to develop the technology of adsorbent synthesis for medical and veterinary purposes by chemical modication of lignin containing wastes on demand. As a raw material, we suggest using large-scale cheap food and technological wastes of industry, in particular: nut shells, grape peel, husk of cereals, buckwheat and sunflower. New combined biosorbents can be synthesized on the basis of a lignocellulosic complex derived from nuclear apricot wastes from the food industry and copper ferrocyanides. It is possible to obtain a number of complex sorbents based on fiber and ferrocyanides of transition metal (Cu2+, Fe3+, Zn2+, Ni2+, Co2+). Cellulose-inorganic sorbents based on white cotton fiber and hydrated pentoxide antimony can be prepared and used for sorption of strontium ions. The hybrid samples can be prepared using hydroformed nanosols and biomacromolecules (DNA, RNA, fibrinogen) and / or natural (starch, chitosan) or synthetic (poly(vinyl alcohol)/poly(ethylene oxide)) polymers that can retain the useful properties of silica and organic matter.
