Polyvinylchloride (PVC) tube based self-propelling shuttle functionalized with Prussian blue (PB) has been developed for cesium (Cs) removal of from aqueous solution. The polydopamine was used as linker improving affinity between PVC tube surface and PB. Self-propelling shuttle was wandering around by Marangoni effect, induced by ethanol infused hydrogel injecting into PVC micro bore of tube. The ethanol released from hydrogel tailors a surface tension difference between media, driving force, on the water surface. The Cs adsorption kinetics of self-propelling shuttle functionalized with PB exhibits much higher performance than stationary system due to the transportation of adsorbent and homogenization by self-propelling, further almost comparable removal of Cs ion to the stirring bar mixing system with non-propelling shuttle.
