Abstract

The invention relates to a nanobubble isotope separation method, a nanobubble isotope separation device and a cascaded unit. The method comprises the following steps: firstly preparing a liquid containing nanobubbles, and then contacting the nanobubbles with liquid in the process of ascending, wherein after the nanobubbles rise to a certain height, a heavier isotope-concentrated product is obtained, and a light isotope-concentrated product is in a liquid phase of a separation cylinder, thereby realizing isotope separation. The separation device comprises a nano-bubble generator, a cylinder separator and a feeding and extracting device. The cascaded unit is composed of a plurality of the separation devices in series-parallel connection. The method, the device and the unit can be applied toisotope separation of various elements, and are especially suitable for separation of light isotopes, especially separation of lithium isotopes. The method, the device and the unit have the advantagesof low investment, low energy consumption, cheap raw materials, high yield, flexible scale, no pollution and the like.
