Chemicals from Wastes : Compost-Derived Humic Acid–Like Matter as Surfactant / P. L. Quagliotto, E. Montoneri, F. Tambone, F. Adani, R. Gobetto, E. Viscardi. - In: ENVIRONMENTAL SCIENCE & TECHNOLOGY. - ISSN 0013-936X. - 40:5(2006), pp. 1686-1692.
Abstract:
Compost humic acid-like (cHAL) polymeric matter (MW 15610), isolated in 12% yield from food and green waste compost, exhibits very good surfactant properties in aqueous solution: i.e., critical micelle concentration (cmc) = 403 mg/L and surface tension at cmc = 36.1 mN/m. Values of cmc are confirmed also by conductivity and phenanthrene solubility measurements. These results, compared with those for other major commercial and research surfactants, propose MAL as a competitive low-cost biosurfactant.
