USING OF BIOMASS AND WASTES OF BEANS (PHASEOLUS VULGARIS) AND PEAS (PISUM SATIVUM) PRO-CESSING AS SORPTION MATERIAL FROM POLLUTANTS REMOVING FROM WATER ENVIRONMENTS (LIT-ERATURE REVIEW)

Abstract

Was reported literature findings of domestic and foreign articles about using of biomass components (leaves, straw, pods, seeds) and wastes of beans (Phaseolus vulgaris) and peas (Pisum sativum) pods shells processing as sorption material for pollutants (metals ions, colorants) removing from water environments. Concise literature findings about Pisum sativum and Phaseolus vulgaris plant structure, cultivation value, and chemical composition of some biomass components are described. Was revealed that composition of beans and peas pods has big amount of proteins, that can provide removing of metals ions such as (Cd(II), Co(II), Cr(III) и Cr(VI), Cu(II), Fe(III), Mo(VI), Ni(II), Pb(II), Sb(III) и Sb(V), Zn(II)) from water environments. Was showed  the possibility of sorption characteristics increase for pollutants by Phaseolus vulgaris and Pisum sativum biomass treatment with different chemical reagents. Was revealed that pollutants sorption isotherms of wastes and biomass of considered legumes are described mostly by Langmuir model than by Freundlich model. The kinetic of process mostly match to pseudo-second order model. It is shown that using of seeds and pods shells of legumes is prospectively for removing of heavy metals ions and suspended particles from water. Was proposed to use charcoal, which was gotten by peas pods carbonization for removing of heavy metals ions from water environments. Concluded, that using of legumes pods extracts is more effective for clearing water environments from heavy metals ions.
