Abstract
Abstract A new series of aniline based polyamines were produced via mannich polycondensation reaction of aniline, formaldehyde and various alkyldiamines. The synthesized polyamines were characterized by solid 13C NMR, FT-IR and elemental analysis. Crystallinity and Surface morphology was investigated by powder X-ray diffraction and SEM-EDX. Thermal stability was tested by thermogravimetric analysis. Adsorption properties toward lead (II) and Arsenic (V) ions was studied by model solutions at controlled conditions (pH, time, temperature and initial concentration). An-Buta polymer showed higher efficacy toward the removal of lead and arsenic ions and was selected to be used in the treatment of wastewater samples and showed efficient removal % of ∼99% and % 85 for lead (II) and Arsenic (V) ions respectively. The results reveal the high potential of the synthesized polyamines to be potential adsorbents for wastewater treatment.
