Polyvinyl chloride Waste as an Adsorbent for the Sorption ofPb2+from Aqueous Solution
Open accessAbstract
The sorption of Pb2+from solution by polyvinyl chloride waste was investigated. The morphological features of the polymer sample were studied using the energy dispersive X-ray spectroscopy (EDX), scanning electron microscopy (SEM), X-ray diffraction spectroscopy (XRD), and the Fourier transform infrared spectroscopy (FTIR). Equilibrium, kinetic, and thermodynamic batch adsorption experiments were carried out by the concentration, time, and temperature effects, respectively. The morphological image of the polymer showed irregular small size particles which indicated a high surface area and porosity that facilitated sorption. The adsorption studies recorded relatively rapid uptake of Pb2+by the polymer which was mainly diffusion controlled and followed a second order kinetic process. The thermodynamic studies suggested relatively low temperature (low energy) favoured sorption which was exothermic with a physisorption mechanism.

Polyvinyl chloride (PVC) waste rapidly adsorbs lead ions from wastewater, achieving effective removal (99%) within 5 min at 30 °C.
“Finally, Wankasi et al. [63] demonstrated the rapid adsorption of lead ions from wastewater using polyvinyl chloride (PVC) waste, achieving effective removal (99%) within 5 min at 30 °C.”

The Results and Discussion report 99% Pb²⁺ removal after 5 minutes and, separately, optimum sorption of 99% at 30 °C. The study describes batch tests in aqueous solution, not wastewater, and does not establish that the 5-minute result was obtained at 30 °C. (LLM, conf=0.88)

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.
