Uranium is an indispensable part of the nuclear industry that benefits us, but its consequent pollution of water bodies also makes a far-reaching impact on human society. The rapid, efficient and convenient extraction of uranium from water is to be a top priority. Thanks to the super hydrophilic and fast adsorption rate of microgel, it has been the ideal adsorbent in water; however, it was too difficult to recover the microgel after adsorption, which limited its practical applications. Here, we developed a uranyl-ion affine and recyclable microgel container that has not only the rapid swelling rate of microgel particles but also allows the detection of the adsorption saturation process by the naked eye.
铀是核工业中不可或缺的一部分，给我们带来了益处，但其对水体造成的污染也对人类社会产生了深远影响。从水中快速、高效且便捷地提取铀成为当务之急。由于微凝胶具有超亲水性和快速吸附速率，它一直是水中理想的吸附剂；然而，吸附后回收微凝胶非常困难，这限制了其实际应用。在此，我们开发了一种铀酰离子亲和且可回收的微凝胶容器，它不仅具有微凝胶颗粒的快速溶胀速率，还能通过肉眼检测吸附饱和过程。
