The inner filter effects and their correction in fluorescence spectra of salt marsh humic matter

- Inner filter effects (IFE) in salt marsh humic fluorescence spectra were studied.
- IFE act differently depending on the type of salt marsh humic acids (SMHA).
- The tryptophan (Trp) band of some SMHA is severally obscured by IFE.
- IFE were studied in mixtures of model fluorophores for SMHA.
- IFE in SMHA spectra were mathematically corrected.
