• ; polyaniline-derived carbon; water purification; Introduction Dyes have been widely used in a wide range of industries including textile, leather and paper, causing serious concern worldwide mainly because of the contamination of water resources. For example, around 700,000 tons of textile dyes are produced

• JGB under a wide range of pH values (from 2 to 12). Results and Discussion Characterization of polyaniline-derived carbon (PDC) The porosity and pore size distribution of the adsorbents were characterized with nitrogen adsorption at 77 K. As shown in Figure 1a, the porosity of the PDC materials was
