Abstract

Marine biofouling remains a big problem of uranium (U(VI)) extraction from seawater. To better utilize sunlight in future, the anti-biofouling properties of typical light sources were evaluated, and ultraviolet (UV) light shows best anti-biofouling capability among studied lights. UV light can damage the cellular structure and intercept the proliferation of marine microorganisms (such as V. alginolyticus), and further control its extracellular polymeric substances (EPS). Microorganism community results clarify that UV light well represses the reproduction and survival of marine microorganisms under different conditions (such as temperature and region), which is in favor of U(VI) extraction. The adsorption capacity of classical U(VI) extraction material poly(amidoxime) (PAO) for U(VI) outstandingly recycled from 47.5 mg/g to 68.5 mg/g after UV irradiated for 12 h at pH 8.2 and 25 °C. UV light can well solve the marine biofouling problem of U(VI) extraction from seawater.

不同光源在解决海水提铀海洋生物污染问题中的应用。

从海水中提取铀（U(VI)）时，海洋生物污染仍然是一个大问题。为了更好地利用太阳光，对典型光源的抗生物污性能进行了评价，其中紫外光的抗生物污性能最好。紫外线可以破坏细胞结构，阻断海洋微生物（如溶藻弧菌）的增殖，并进一步控制其胞外聚合物质（EPS）。微生物群落结果表明，紫外光在不同条件下（如温度和区域）对海洋微生物的繁殖和生存有较好的抑制作用，这有利于U（VI）的提取。经典的U（VI）提取材料聚偕胺肟（PAO）在pH 8.2、25℃条件下紫外照射12 h后，对U（VI）的吸附量从47.5 mg/g降至68.5 mg/g。紫外光可以很好地解决海水中提取U（VI）的海洋生物污染问题。
