Influence of one-step and two-step KOH activation on activated carbon characteristics
Open accessAbstract
Abstract This study investigated the influence of one-step and two-step KOH activation on the characteristics of activated carbons. The biomass precursors [Kanlow Switchgrass (KS) and Public Miscanthus (PM)] and their biochars produced at pyrolysis temperature of 500 °C, were impregnated with KOH and activated at a temperature 900 °C for 30 min in an inert condition. BET surface area, pore characteristics, surface functional groups and microstructures of the activated carbons were examined. The biomass-derived activated carbons (KOH-KSBM and KOH-PMBM) had the highest BET surface areas of 1272 and 1597 m2/g respectively. The activated carbons were used in adsorbing acetaminophen and caffeine and the biomass-derived activated carbons presented an overall better adsorption characteristic.

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.
