DBSA doped polyaniline/multi-walled carbon nanotubes composite for high efficiency removal of Cr(VI) from aqueous solution

[Display omitted] •DBSA doped polyaniline/MWCNTs composite was synthesized.•DP/MWCNTs showed higher efficiency for Cr(VI) than the pristine and oxidized CNTs.•The removal of Cr(VI) was highly depends on solution pH.•The experimental data was analyzed using isotherm and kinetic models. Dodecyl-benzen...
