<p>Powderized, comminuted or granular materials are made hydrophobic or water repellent and simultaneously oleophilic or oil attracting by first mixing the materials with a chromium salt solution and then adding to the mixture a bridging agent such as a thermoplastic hydrocarbon which envelopes the material particles. These materials are especially suitable for the clean-up of oil spills.</p> |
