Abstract :

In this study performed about the absorbent materials commonly used in cleaning up oil spills on water surface, wastes of granular styrofoam, tea fibers and polystyrene foam were used as adsorbent materials. The capacities of adsorbents on adsorbing oils of Adıyaman and Kerkük in water and in salty water have been determined based on the ASTM F726-06 method. The specific surface areas have been identified based on the BET method. According to the results of the test, the highest specific adsorption capacity of each adsorbent has been provided within 0.4 g amount of adsorbents. According to the test duration of 24 hours, the specific adsorption capacities of adsorbents for the oils of Adıyaman and Kerkük, were determined as 8.06 and 5.32 g of adsorbed oil/g adsorbent for styrofoam, 15.63 and 13.16 for tea fiber and 41.46 and 39.01 for polystyrene foam respectively. As far as the salty water conditions are concerned, specific adsorption capacities of adsorbents for the oils of Adıyaman and Kerkük were determined as 6.94 and 4.40 g of adsorbed oil/g adsorbent for styrofoam, 12.07 and 11.54 for tea fiber and 35.21 and 32.27 for polystyrene foam respectively. According to results of the tests, the specific adsorption capacity of polystyrene foam having the the largest surface area was determined higher than the specific adsorption capacities of granular styrofoam and tea fiber.
