Abstract
A standard humic acid extraction procedure has been used to isolate da rk brown organic residues from samples of the macroscopic marine brown alga Pilayella littoralis. The residues are insoluble in water, but s oluble at high pH, and are similar in elemental composition, ash conte nt, UV-visible, IR, PMR and X-Ray fluorescence spectra, X-Ray diffract ograms and scanning electron micrographs to residues of a humic acid i solated from municipal compost. These results indicate that Pilayella produces humic acids.
