Abstract
Total petroleum hydrocarbon (TPH) removal and temperature variations in bunker fuel oil C contaminated soil were investigated by using microwave radiation in the presence of triiron oxide or activated carbon as a heating element. Temperature increments of were observed, when 100~500 watt of microwave radiation was applied for the contaminated soil in the presence of triiron oxide or activated carbon. Temperature variation of the soil was more rapid in the presence of triiron oxide than activated carbon. 10% or 25% of heating element content was required to reach the temperature of thermal desorption for triiron oxide and activated carbon respectively. After radiation, 44.1% and 89.4% of initial TPH in soil was removed in the presence of triiron oxide and activated carbon respectively. It was observed that activated carbon was more reactive than triiron oxide for the removal of high molecular carbon of bunker fuel oil C.
