Adsorption of Ni(II) from Aqueous Solution Using Oxidized Multiwall Carbon Nanotubes
Abstract
In this work, oxidized multiwall carbon nanotubes (MWCNTs) were used as a novel adsorbent for removing Ni(II) from aqueous solution. The adsorption of Ni(II) onto oxidized MWCNTs was studied as a function of contact time, pH, ionic strength, MWCNT concentration, and temperature. The results showed that Ni(II) adsorption onto MWCNTs is strongly dependent on pH and oxidized MWCNT concentration and, to a lesser extent, ionic strength. Kinetic data indicated that the adsorption process achieved equilibrium within 40 min and follows a pseudo-second-order rate equation. The adsorption data fit the Langmuir model and its linearized form well, together with thermodynamic data indicating the spontaneous and endothermic nature of the process. Results of a desorption study showed that Ni(II) adsorbed onto oxidized MWCNTs could be easily desorbed at pH <2.0. Ion exchange may be the predominant mechanism of Ni(II) adsorption on oxidized MWCNTs. Oxidized MWCNTs may be a promising candidate for concentration of heavy metal ions from industrial wastewater.

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.
