Activated carbon nanofibres from gum kondagogu for remediation of toxic metals

Original language description

Activated carbon (AC) from gum kondagogu (GK), a natural tree gum, was prepared by acarbonization/chemical activation process. The nanocomposite fibres contain AC, poly vinyl alcohol (PVA)and GK, which were fabricated by electrospinning. The system and the process parameters of theelectrospinning were optimised to obtain smooth and uniform AC-GK/PVA composite nanofibres. Thecomposite nanofibres with a mean diameter of 250±55 nm were obtained after cross-linking with heattreatment. Hydrophobic composite nanofibres of AC-GK/PVA were created using methane plasmatreatment. Various microscopic and spectroscopic characterization techniques were used to characterize thecomposite nanofibres. The adsorption efficiencies of both AC-GK/PVA and GK/PVA composite nanofibreswere tested on toxic metal contaminants (Pb2 , Cd2 , Cu2 , Ni2 , Zn2 , total Cr and As) in an aqueous solutionand were assessed quantitatively using ICP-AES and ICP-MS. The renaissance and reusability of thecomposite nanofibres for consecutive operation were evaluated. The large surface area to volume ratio,extremely high stability, multi-functional groups and increased hydrophobic character of the prepared ACGK/PVAcomposite nanofibres were found to be the key factors for the high adsorption/removal of toxicmetals contaminant from the aqueous environment
