Synthesis, characterization of Fe3O4@glycine doped polypyrrole magnetic nanocomposites and their potential performance to remove toxic Cr(VI)

다국어 초록 (Multilingual Abstract)

Fe3O4 coated glycine doped polypyrrolemagnetic nanocomposite (Fe3O4@gly-PPy NC) was prepared viacoating of suspended Fe3O4 nanoparticles with gly-PPy. FE-SEM and HR-TEM images indicated thatFe3O4 nanoparticles were encapsulated by precipitating gly-PPy moieties. Chromium(VI) adsorptionfollowed a Langmuir isothermwith maximum capacity of 238–303 mg/g for a temperature range of 25–45 ℃ at pH 2. The adsorption process was governed by the ionic interaction and the reduction of Cr(VI) toCr(III) by the PPy moiety. Results showed that NCs are effective adsorbents for the removal of Cr(VI) fromwastewater and can be separated by external magnetic field from the reactor.
