Removal of methyl orange from aqueous solution using SRB supported Bio-Pd/Fe NPs

H Kubendiran, D Hui, M Pulimi… - Environmental …, 2021 - Elsevier
Removal efficacy of biogenically (Desulfovibrio desulfuricans) synthesized bimetallic Pd/Fe
nanoparticles on the toxic azo dye Methyl Orange (MO) was evaluated using DM and natural
water bodies. Nanoparticle concentration and conditions were optimized using response
surface methodology (RSM). Biogenic Pd/Fe nanoparticles exhibited higher removal
(96.16±1.6%) efficiency in just 30 min. The role played by D. desulfuricans and Pd catalyst in
MO removal was also assessed and 36.8±1.4% removal by D. desulfuricans and …
