Biosorpce chromu Cr (VI) z vodných roztoků na poloprovozně upravený biosorbent z rostlinné biomasy

Abstract

The thesis is focused on the research of sorption of ions Cr (VI) from aqueous solutions on activated by pilot biosorbents from plant biomass. Biosorbents was used as a plant Reynoutria japonica. The theoretical part is an introduction to the problems of removing heavy metals from aqueous solutions and an overview of sorbents, which are used for sorption of Cr (VI). Methodological part contains research of sorption Cr (VI) with an activated (0.1M HCl) and nonactivated sorbent on two devices (magnetic stirrer, shaker) at pH values (2 to 4) in dependence on time. Results include annotated tables and graphs and accompanied by mathematical models.
