Enhanced flushing mechanism of petroleum hydrocarbon contaminated sandy soil by air nano bubbles
Chunjiang Liu, Minghui Xiang, Chen Yang, Yiran Chen, Zhongyuan Li, Wu Wang, Wei Yin, Hui Li, Yuan HuangThe NBs have the best removal rate of petroleum hydrocarbon pollutants in porous media under weakly alkaline condition (pH = 7–8). Both strong acidity and strong alkalinity are not conducive to the flushing removal of pollutants.
