Abstract

ABSTRACT The present study is concerned with the use of a novel nanoporous carbon material (MNC) produced from mandarin (Citrus reticulata) industrial processing waste (MW) for the removal of textile dyes as cationic dye, methylene blue (MB) and anionic dye, metanil yellow (MY), from the aqueous solution. The adsorption mechanisms were examined by SEM and FT-IR analysis. For two dyes, the kinetics was well described by the pseudo-second-order model, whereas the isotherms were all best-fitted by the Langmuir model, and the maximum monolayer adsorption capacity for MB and MY dyes were 313 and 455 mg g−1, respectively.
