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)

Abstr anthracene chars heat treated between 500 and 1200Β°C is developped and applied to d.c. electrical conductivity, paramagnetic susceptibility and apparent density. An inhomogeneous process for the carbonization is proposed, in agreement with recent results on the structure of these chars. acts 3
