Raw and processed dataset for agricultural waste-derived biochars characterization and lead (Pb) adsorption

OverviewThis repository contains the primary experimental datasets, spectroscopic profiles, and thermal analyses underlying the manuscript: "Environmental applications of agricultural waste-derived biochars for soil improvement and lead adsorption" submitted to Acta Agriculturae Slovenica. File Inventory & Resource MappingThe uploaded Origin Project (.opju) files correspond directly to the results, figures, and tables discussed in the manuscript: 1. TOC, TN , P and K Analysis.opju: Contains the raw values and replicates for total organic content (TOC), total carbon content, phosphorus (P), and potassium (K) content. All other broad chemical properties are fully detailed within the article's tables.2. Lead Removal Studies.opju: Includes the numerical matrices for lead (Pb) adsorption equilibrium, kinetics data, and isotherm modeling parameters.3. X-ray Differactograms.opju: The raw intensity data points (2-theta versus counts) showing the crystalline structure phase identification of the biochars.4. Fourier Transform Infrared Spectra.opju: Spectroscopic transmission/absorbance data points across the wavenumber spectrum (4000–400 cm⁻¹) used for functional group identification.5. Thermogravimetric Analysis.opju: Thermogravimetric weight loss percentage and derivative data (DTG) as a function of temperature under thermal degradation. Software RequirementsThese files were created using OriginPro. They can be fully opened, inspected, and recalculated using OriginLab software.
