Conversion of Poly(Ethylene Terephthalate) Waste into Activated Carbon: Chemical Activation and Characterization
Abstract
Due to its high carbon content, low impurities, low cost and easy availability, poly(ethylene terephthalate) (PET) waste is considered as a suitable precursor for the production of activated carbon. The chemical activation of PET wastes using different chemical agents such as H 3 PO 4, H 2 SO 4, ZnCl 2, and KOH was investigated. KOH‐ and ZnCl 2‐activated PET were found to be the best choices for the adsorption of small and large molecules. The capacities of the adsorbents towards I 2, methylene blue, N 2, CH 4, and CO 2 followed the order KOH‐PET >H 3 PO 4‐PET > ZnCl 2‐PET > H 2 SO 4‐PET; however, in the molasses uptake and selective adsorption of CO 2 compared to CH 4, ZnCl 2‐PET performed better than the other adsorbents.

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.
