Raw data for FT-ICR MS spectrometry

The integration of oxidation and membrane technologies demonstrates significant potential in shale gas wastewater (SGW) treatment. However, the molecular-level transformation mechanisms of the complex dissolved organic matter (DOM) in SGW during this coupled process remain unclear. This study systematically assessed the performance of UV/H₂O₂-ultrafiltration (UF)-reverse osmosis (RO) combined process in removing contaminations from SGW and used Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) to elucidate the transformation characteristics and mechanisms of DOM during treatment.
