✦ Synopsis

Humic substances in aqueous solution undergo characteristic alterations when irradiated with light of wavelengths>290 nm. Humic substances subjected to a preliminary irradiation are less capable of generating reactive oxygen species. This effect is illustrated by changes in spectroscopic (u.v., ESR) and other physical properties of the samples.

## Abstract This communication reports a study of the effect of ionic strength and electrolyte composition on fractions, separately collected by flow FFF, of a mixture of humic substances. Reverse phase HPLC analysis of three early eluting fractions suggests that the components released by the colu
