  3. Abstract:
  4. The present study examined the sorption capacity and sorption kinetics of four-type perlite for oil spills clean up. These four types are different on their porous space, expansion ability and special surface area. The tests were done both in static and dynamic methods. Experiments showed that the perlite spread on oil spill rapidly and floated on the surface of oil spill because of its low density (80-180 kg/m3). Scanning Electron Micrograph (SEM) of a typical structure of expanded perlite showed that it of high porous space. Sorption kinetic of oil spill into porous expanded perlite was evaluated by weight increase of crude oil with sorption time. According to kinetic study sorption of oil spill takes place in the initiation of spreading of perlite on oil spill. The second order modeling fits the experimental data much better then the other models. In this case, the correlation coefficient values are much closer to 1. One of the perlite types, A0, clotted during sorption process and could easily be collected from the surface of water in this situation it. Sorption capacity for this perlite is 7.3gr oil/1 gr perlite
