Resumen
Nanobubbles were manufactured by using pressurized hydrogen gas and were applied to soils contaminated with heavy metals, to confirm their function as enhancers. The manufactured nanobubbles remained for an extended period of time. A batch-test experiment revealed that the nanobubbles improved desorption of heavy metals. In addition, when the nanobubbles were used as enhancers in electrokinetic experiments, the nanobubbles had better remediation effects than distilled water (DW). The remediation of heavy metals is expected to have a significant impact when using the nanobubbles.
