SPB-500 exhibits rapid equilibrium, favorable Freundlich isotherm behavior, pseudo-second-order kinetics, and good regeneration stability.
“rapid equilibrium, favorable Freundlich isotherm behavior, pseudo-second-order kinetics, and good regeneration stability”
From Integrated Techno-Economic, Environmental Screening, and Social Return on Investment Analysis of Community-Scale Sawdust–Polypropylene Co-Pyrolysis for Heavy-Metal Adsorbent Production in Rural Area, Thailand (2026) · cites this paper as [25]
The Results and discussion report favorable adsorption according to Freundlich parameters, a high-correlation pseudo-second-order fit, and SPB-500 retaining about 73% adsorption efficiency after five regeneration cycles. They describe rapid initial uptake in the first 30–40 minutes followed by a slower approach to equilibrium, not rapid attainment of equilibrium. Freundlich and conventional pseudo-second-order models were not the best-fitting models. (LLM, conf=0.86)
Experimental — accuracy not yet measuredSPB-500 has a maximum Cu2+ adsorption capacity of 126.1 mg g−1.
“SPB-500 exhibited excellent Cu 2+ adsorption performance, including a maximum adsorption capacity of 126.1 mg g -1”

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.
