Fourier-transform ion cyclotron resonance mass spectrometry (FT-ICR MS) data of wastewater effluent organic matter (EfOM).

Processed and quality checked FT-ICR MS data for original (nEx) and PPL extracted (Ex), as well as non-ozonated (nOz) and ozonated (Oz) DOM from a waste water treatment plant sample. Sampling and measurement conditions are described in the companion paper (Jennings et al. 2022, doi:10.1021/acs.est.1c04310). Direct infusion (DI) and LC-FTICR MS data are included. For LC data, the segment numbe (Range#) as well as the retention time range (in min) are indicated.
