Aminated Polyacrylonitrile Fibers for Lead and Copper Removal
Abstract
Aminated polyacrylonitrile fibers (APANFs) were prepared through the reaction of polyacrylonitrile fibers (PANFs) with diethylenetriamine in a solution and were used as an adsorbent to remove lead and copper ions from aqueous solutions. It was found that the zero ζ potential point of the APANFs was at about pH = 8.1, in contrast with that of the PANFs at pH = 3.6, and the APANFs had significantly higher adsorption capacities for both lead and copper ions than the PANFs. The adsorption behaviors of lead and copper ions on the APANFs depended upon the solution pH values, and greater amounts of adsorption were obtained at higher solution pH values. Scanning electronic microscopy and atomic force microscopy indicated that the APANF had a rougher surface than the PANF, and the adsorption of the metal species on the APANF made the surface even rougher. Fourier transform infrared spectroscopy revealed that the amine groups on the surface of the APANF played an important role in the removal of lead and copper ions from the solutions. X-ray photoelectron spectroscopy for the APANFs before and after lead and copper adsorption indicated that the adsorption of lead and copper ions on the APANFs can be mainly attributed to the formation of metal complexes with the nitrogen atoms in the amine groups on the surfaces of the APANFs, although the hydroxyl groups on the APANFs may also be involved in binding lead ions from the solutions.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
