Biosorption Of Cr(Iii) Ions From Aqueous Solutions At Plant-Activated Biosorbents

The study is focused on biosorption of Cr(III) ions from aqueous solutions at plant activated biosorbents prepared from Reynoutria japonica. The aim of the work was to find a suitable biosorbents for activation, as well a suitable pH and concentration of Cr(III) ions in aqueous solution for efficient biosorption process. From the measured results were compiled Langmuir's and Freundlich's models. The best results are achieved biosorbent sample 0.5 at maitaned pH 5.
