A point-and-click 'Shiny' interface to the 'biocharkit' package. Lets a user upload Excel workbooks of biochar characterisation and batch adsorption data, map spreadsheet columns to the required variables via dropdown menus, and run sample-ID parsing, adsorption capacity and removal efficiency calculations, isotherm fitting (Langmuir, Freundlich, Temkin, Dubinin-Radushkevich, Sips), kinetics fitting (pseudo-first/ second-order, Elovich, intraparticle diffusion), van't Hoff thermodynamics, batch fitting across many samples at once, FTIR baseline correction, automatic peak picking and functional-group analysis, XRD peak deconvolution and crystallinity index, BET surface area, TGA analysis (DTG curve with auto-detected decomposition peaks, moisture/volatile-matter/ash/fixed-carbon straight off a curve for a single sample or in batch across many, and Kissinger non-isothermal kinetics from multi-heating-rate data), proximate/ultimate analysis, and correlation matrices, without writing any R code. Results and 600 dpi TIFF figures can be downloaded directly from the browser, along with a combined analysis report.
