 ABSTRACT

In the present study, Pisum Sativum (Green pea) pod were converted to biochar with slow pyrolysis at 450°C and utilized for hexavalent chromium removal from aqueous solution. Batch adsorption studies were carried out to evaluate the effect of initial pH, biochar dosage, initial Cr (VI) concentration and contact time. The highest removal of Cr (VI) was achieved at pH 2.0 using a 4 gm/L of biochar dose with 10 mg/L of Cr (VI) concentration. The Langmuir isotherm model was fitted best with maximum uptake capacity of 33.33 mg/g. FTIR analysis was carried out for GPPB450 before and after Cr (VI) adsorption to understand the role of functional moieties.

Key words: Biochar, Adsorption isotherm, Hexavalent chromium, Pea pod
