首次了提出纳米气泡同位素分离方法, 并通过实验实现了氢、氧、碳和锂等轻同位素的分离, 测得了分离系数, 验证了该方法的科学性和有效性. 研究揭示了纳米气泡同位素分离过程首先发生在由于快速塌陷式绝热自收缩形成纳米气泡时,可能因高温或纳米表面效应作用引起表面分子离解, 而使气泡表面带负电荷对周围介质的吸附过程中, 并且也出现在后续纳米气泡与特定溶液组成分离体系的同位素 (离子) 化学交换过程中, 它具有双重分离效应. 由于纳米气泡的形成是一个快速过程, 并且气泡在溶液中的离子交换是同位素共振交换化学反应, 过程也很快达到平衡, 两者共同决定了纳米气泡同位素分离可能是一种平衡时间很短的分离方法, 克服了通常化学方法平衡时间长的缺点. 在研制成纳米气泡分离原型单机的基础上, 本文也设计了纳米气泡同位素分离级联, 增加分离效果, 以获得各种丰度的同位素, 从而说明其工业化生产的可能性.

This study proposes the nanobubble isotope separation method for the first time. The separation of light elements such as hydrogen, oxygen, carbon, and lithium is realized via experiments, and the separation coefficient is measured, which verifies the scientificity and effectiveness of the method. The study revealed that the isotope separation process of nanobubbles not only occurs when the rapid collapse adiabatic self-shrinkage forms nanobubbles, which causes the dissociation of surface molecules possibly owing to high temperature or nano-surface effects, such that the surface of the bubbles is negatively charged and adsorbs the surrounding medium, but also occurs in the subsequent isotope (ion) chemical exchange process between nanobubbles and specific solutions to form a separation system, which has a dual separation effect. Because the formation of nanobubbles is a rapid process, and the ion exchange between bubbles and solution is an isotopic resonance exchange chemical reaction, the process also quickly reaches equilibrium. The bubbles and solution determine that nanobubble isotope separation is a separation method with a short equilibrium time, overcoming the shortcomings of the usual chemical method balance time. Based on the prototype stand-alone machine for nanobubble separation, nanobubble isotope separation cascades are also designed to increase the separation effect to obtain isotopes of various abundances, thereby illustrating the possibility of industrial production.
