KINETIC AND EQUILIBRIUM STUDIES OF CR(III) AND CR(VI) SORPTION FROM AQUEOUS SOLUTION USING ROSA GRUSS AN TEPLITZ (RED ROSE) WASTE BIOMASS

The biosorption of Cr(III) and Cr(VI) from synthetic solution using dried untreated and pretreated Rosa gruss an teplitz waste biomass was evaluated in this study. The results showed that initial pH, biosorbent dose, sorbent particle size, initial metal concentration, time and temperature affected c...

The results showed that initial pH, biosorbent dose, sorbent particle size, initial metal concentration, time and temperature affected chromium uptake capacity of rose biomass. The effect of twenty different pretreatments including gaseous and other reagents on Cr(III) and Cr(VI) uptake capacity of Rosa gruss an teplitz waste biomass was comprehensively described. Uptake capacity of Rosa gruss an teplitz waste biomass was significantly affected after pretreatment. The metal uptake capacity of biomass was not only found related to nature of pretreatment but also found strongly related to oxidation state of chromium. The estimation of the correlation coefficients for Cr(VI) showed that the experimental data fit better to Freundlich model.

Biosorption of Cr(III) and Cr(VI) ions on to biomass followed pseudo 2ntl order adsorption kinetic model. The results confirmed that rose waste biomass is a potential biomaterial to remove Cr(III) and Cr(VI) ions with a high biosorption capacity 45.03 mg/g and 48.75 mg/g for Cr(III) and Cr(VI) respectively.info:eu-repo/semantics/openAccessSociedad Chilena de QuímicaJournal of the Chilean Chemical Society v.53 n.4 20082008-12-01text/htmlhttp://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0717-97072008000400006en10.4067/S0717-97072008000400006
