Deposit-resolved Taguchi design, kinetics, and spectroscopy datasets for fulvic-acid recovery from coal gangue via H₂O₂ oxidation

This dataset contains the experimental design matrix, replicate fulvic-acid (FA) yields, kinetic time-series tables, Arrhenius-derived temperature dependence, and supporting characterization summaries for deposit-resolved FA recovery from four coal-gangue sources (GLC, NEC, SGC, SMC) using single-oxidant H₂O₂ oxidation. The study compares deposit-specific oxidation windows using a Taguchi L9(3⁴) orthogonal design with confirmation runs, links yield to acidity and surface functionalization, and reports pseudo-first-order kinetic parameters and apparent activation energies across 40–80 °C. The files enable independent verification of yield optima (including the order-of-magnitude yield contrast across deposits), reproduction of kinetic/Arrhenius calculations, and reuse of derived structural indices (fluorescence, UV–vis, XPS C1s fractions) for meta-analysis and process–structure modeling. This dataset contains design matrices/yield tables, kinetics/Arrhenius tables (where provided), response-surface modeling outputs (coefficients, diagnostics, OriginPro NLFit reports/templates), and supporting documentation used in a coal-gangue → fulvic-acid (FA) recovery study based on single-oxidant H₂O₂ oxidation. Files are organized into data and report folders for direct reuse and verification of modeling/optimization steps.
