Abstract

In the present study, the UiO-66-NH 2 MOF synthesized by microwave heating method was incorporated into the PAN/chitosan nanofibers for the removal of Pb(II), Cd(II) and Cr(VI) ions through the adsorption and membrane filtration processes. The synthesized MOFs and nanofibers were characterized using XRD, BET, FTIR, SEM, and DSC analysis. The effect of UiO-66-NH 2 MOF content (0-15 wt.%), pH (2-7), contact time(5-90 min), metal ions initial concentration (20-1000 mg/L) and temperature (25-45 °C) was studied on the metal ions adsorption using PAN/chitosan/UiO-66-NH 2 nanofibrous adsorbent. The kinetic, isotherm and thermodynamic parameters were evaluated to understand the metal ions adsorption mechanism using nanofibers. The Pseudo-second-order kinetic and Redlich-Peterson isotherm model were well described the experimental sorption data. In the heavy metal ions membrane filtration process, the different parameters such as MOF concentration (2-15 wt.%), membrane thickness (10-70 μm), metal ions concentration (5-50 mg/L), temperature (25-45 °C) and filtration time (1-24 h) were investigated on the performance of PVDF/ PAN/chitosan/UiO-66-NH 2 nanofibrous membrane toward metal ions removal. The high water flux and high metal ions removal within 18 h filtration time showed the high potential of PVDF/ PAN/chitosan/UiO-66-NH 2 membrane for the removal of metal ions from aqueous 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.
