Electrospun Hybrid Nanofibers As Nano Adsorbent For Effective Removal of Cd2+ From Polluted Water

In this research, a new novel three dimensional material was produced through the combination of cnt, graphene and pan/ttip and effect of mwcnt and graphene hybridization on tio2 nanofibers was studied. tio2/pan (mwcnt/go) g pca nanofibers were synthesized using multi wall carbon nanotubes graft poly citric acid (mwcnt g pca), graphene oxide graft poly citric acid (go g pca) and poly acrylo nitrile (pan)/titanium tetra isopropoxide precursors (ttip) by electrospinning technique. the effective parameters such as the (mwcnt/go) g pca content, applied voltage, distance between needle and collector, (ttip/pan) precursors contents and feed rate were optimized. the nanofibers were produced with the best morphology at optimum conditions and characterized by ftir, tg dta, sem and xrd analysis. prepared nanofibers after calcination process used as nano adsorbent for complete removal of cadmium ions from polluted water successfully. the adsorption isotherms, thermodynamics and kinetic studies were done for nano adsorption process. the langmuir and freundlich isotherms were applied for isotherm study. desorption adsorption studies were done at optimum condition.
