Emulsion and Sorption Oil Spills by Expanded Perlite types: A0

In this study ;four types of expanded perlites (A0, A1, AH, A2) were used to sorption oil spill. These Jour types are different on their porous space, expansion ability and special surface area. The tests were done in laboratory bench scale and in static and dynamic models. Experiments show that perlite is spread on oil spill rapidly and is floated on the surface of oil spill because of its low weight (40-200 kg/m^3) and high porous space. According to kinetic study sorption of oil spill is took place in the initiation of spreading of perlite on oil spill. One of the perlite types, A0, is clotted during sorption of oil spill and in this situation is removed from the surface of water easily. A0 sorption capacity is 7ml oil/1gr perlite. A0 can emulsify oil spill that is 25 times heavier than its own weight, so that microorganisms can degrade it readily.
