Popis: The aim of this study is to investigate the utilization of scoria as PRB reactive media for the removal of petroleum hydrocarbon from groundwater. Tests of comparison of scoria with powdered activated carbon(PAC) show that scoria has a larger capacity for petroleum hydrocarbon sorption than PAC. The particle size has weak effect on purification petroleum contaminated groundwater. The results of isothermal adsorption test show the high sorption capacity of the scoria(1.7g/g for TPH).The acquired sorption data are well fitted to the Langmuir isotherm.Careful examination of scoria’s composition and microstructure suggests that the sorption behavior is not only physical sorption but also chemical sorption,but mainly controlled by physical sorption .We recommend scoria as an economic,efficient and environmental friendly sorbent for petroleum hydrocarbon in contaminated groundwater.
