Abstract

The effective extraction of uranium (U(VI)) from seawater is critical for the development of nuclear energy in the near future. Biofouling is one of the core problems of U(VI) extraction from seawater that must be solved soon. In this work, plasma technology is applied to solve the biofouling problem of U(VI) extraction from seawater. The experimental results show that reactive oxygen species (ROS) formed during the plasma discharging process can effectively kill marine microorganisms in 30 min by destroying their membrane structure and removing their extracellular polymers (EPS), which can improve its U(VI) adsorption capability. Plasma treatment also significantly affects the microorganism compositions in natural seawater and can effectively kill Proteobacteria species including Vibrio alginolyticus. In summary, plasma sterilization is fast, effective, and simple. It can solve the biofouling problem and simultaneously improve the recovery capability of poly(amidoxime) (PAO)-based materials for U(VI) from seawater.

利用等离子体技术解决从海水中提取铀的生物污染问题

从海水中有效提取铀（U(VI)）对未来核能的健康发展至关重要。生物污损是海水提取铀（VI）必须尽快解决的核心问题之一。在这项工作中，等离子体技术被应用于解决从海水中提取铀（VI）的生物污垢问题。实验结果表明，等离子体放电过程中形成的活性氧（ROS）可在 30 分钟内破坏海洋微生物的壁膜结构，去除其胞外聚合物（EPS），从而有效杀灭海洋微生物，并显著提高其对六价铀的吸附能力。等离子处理对海水中的微生物组成也有显著影响，可有效杀死包括溶藻杆菌在内的变形菌。总之，等离子杀菌是一种快速、有效、简单的工艺。它可以很好地解决生物污垢问题，同时提高 PAO 基材料从海水中回收铀（VI）的能力。
