摘要

We applied a photo-responsive Langmuir-Blodgett (LB) film to selective isolation of uranyl cation from aqueous solutions. Uranyl cation was isolated onto a quartz plate covered with 5-octadecyloxy-2-(2-pyridylazo)phenol (PARC 18) LB film which possesses the potential to form a complex with transition metal cations. The isolation process could be switched on by photoillumination. On the other hand, lanthanides (La, Ce, Nd, Gd, Er and Yb) were hardly isolated onto this film. Therefore, it was suggested that uranyl can selectively be collected from mixed solutions containing uranyl and lanthanides and that this process can be controlled by photoillumination. Detection limit of uranyl concentration in this system was also determined to be about 1.5 ppb.
