Influence of chemical structure of dyes on capacitive dye removal from solutions

Polypyrrole nanofibers (PPy-NF) were prepared by an oxidative template assembly method and utilized for the fabrication of N-doped activated carbon nanofibers (N-AC-NF). Capacitor cells, containing N-AC-NF electrodes were used for capacitive dye removal (CDR) from aqueous solutions. It was found that CDR method can be used for the removal of triphenylmethane and chromotropic acid family dyes from aqueous solutions. The analysis of cyclic...
