Tóm tắt

Composites based on polyaniline (PANi) and sawdust (SD) were prepared by chemical method from acid medium containing aniline using ammonium persulfate as oxidation agent. It was found by IR-spectroscopy a clearly presence of PANi combined with sawdust formed composite which having morphological structure in nano scale by SEM-images. Cr (VI) concentrations in solution berore and after adsortion process on that composite were ana lysed by Atomic Absorption Spectroscopy. Optimum conditions for Cr(VI) removal were found to be pH 3, equilibrium time of 50 minutes, the maximum adsorption capacity (Qmax) of PANi/SD for Cr(VI) was 90.09 mg/g.
