Data and code supporting the study of photocatalytic transformation of 2,4-D by copper-modified tungstophosphoric acid supported on natural zeolite

It contains processed HPLC data supporting the reported decrease in the integrated peak area of parent 2,4-D, processed FT-ICR MS data and derived evidence tables used for confidence-ranked composition/family assignments and harmonic-artifact assessment, material-characterization data, and computational chemistry inputs, outputs and derived datasets supporting the reported electronic-structure and polyoxometalate analyses.

The package also includes historical analysis code, provenance records, metadata, SHA-256 manifests and documentation of analytical limitations. The deposited materials support parent-compound disappearance and bounded MS/computational interpretations; they should not be interpreted as evidence of complete mineralization, complete detoxification, or unambiguous structural identification of all FT-ICR candidate species.
