Phytoremediation of Soil Contaminated with Used Lubricant Oil Using Spathiphyllum spp.
Soil contamination with used lubricating oil from automobiles is a growing concern in many countries, especially in Asian. This research was conducted on a laboratory scale. The plant used in this research was Spathiphyllum spp. in comparison with controlled (no-plant). The size of reactor used in this research was set at 20 cm width, 20 cm length, and 40 cm height with working volume of the reactor was 0.016 cm3. Moreover, a pH value was controlled in a range of 7 to 8. The soil contaminated with used lubricant oil collected from automobile shop in Nonthaburi province. Soil contaminated and treated soil were extracted by solid-phase extraction (SPE) and analyzed by gas chromatography with mass spectrometer (GC–MS). The results showed that Spathiphyllum spp. could be growth during time operation. Spathiphyllum spp. has a potential in reclaiming hydrocarbon-contaminated soil such as Benzene, Toluene, Ethylbenzene, and Xylene (BTEX) approximately 20 to 60 days operation.
