    Abstract The present study has explored the adsorption properties of polypyrrole-based adsorbents (polypyrrole and polypyrrole-polyethyleneimine composite) as novel conducting polymers in adsorbing methyl orange (MO) (an anionic dye) effectively from aqueous solution. The adsorption characteristics of the prepared polymer-based adsorbents were characterized by BET, FTIR, FESEM, and XRD methods. The effectiveness of PPy-based adsorbents for MO dye adsorption was examined using the batch adsorption method. Different parameters were changed during the adsorption process, including contact time, solution pH, and adsorbent dosage. The highest BET surface area of the PPy-PEI composite was found to be 11.85 m2 /g,… More >
