Adsorption and coadsorption mechanisms of Hg2+ and methyl orange by branched polyethyleneimine modified magnetic straw

•Branched polyethyleneimine modified magnetic straw was prepared.•Hg2+ adsorption arose through formation of chelate complex.•MO adsorption occurred primarily due to electrostatic interaction.•The presence of methyl orange significantly enhanced the adsorption capacity of Hg2+. Adsorption and coadso...
