  • Abstract
    در اين مطالعه تهيه و به كارگيري نانوكامپوزيت پلي پيرول به عنوان جاذب يونهاي مس از محلول هاي آبي مد نظر بوده است. پلي پيرول با بهره گيري از روش پليمريزاسيون اكسايشي پيرول و با اكسنده Fecl3 توليد شده است. هدف اين بررسي حذف مس دو ظرفيتي بوده با استفاده از نانوكامپوزيت هاي پلي پيرول-Tio2 و پلي پيرول- Tio2-DHSNa بوده است. مطالعات شكل شناسي جاذب مذكور با آزمايشات SEM و FTIR مورد سنجش قرار گرفته است. اثر پارامترهايآزمايشگاهي چون pH، دز يون و زمان تماس در يك سامانه غيرپيوسته بررسي و مقادير بهينه براي pH عدد 3، براي دز يون 50 ميلي گرم بر ليتر و براي زمان تماس 30 دقيقه به دست آمد. ضمنا داده هاي تجربي با مدل ايزوترم فرندليچ تطابق بهتري نشان داده است.
  • Abstract
    In this article, preparation of polypyrrole and its nanocomposites as adsorbents were discussed and the capability of separation of copper ions from aqueous solution were studied. Polypyrrole was prepared by chemical oxidative polymerization method of pyrrole using FeCl3 as an oxidant. The removal of Cu (II) was investigated using PPy, PPy/TiO2 and PPy/TiO2/DHSNa nanocomposites. The products were investigated in terms of morphology and chemical structure with scanning electron microscopy (SEM) and Fourier-transform infrared spectroscopy (FTIR). Batch studies were performed to evaluate the influence of various experimental parameters such as pH, ion dosage and contact time. Optimum conditions for copper ions removal were found to be pH 3, ion dosage of 50 mg L-1 and the equilibrium time equals to 30 minutes. It was also found that the equilibrium adsorption isotherm was better described by Freundlich adsorption isotherm model.
