摘要
in our previous paper we reported the complex of Eu<sup>3+</sup> with 18-crown-6（18-C-6）giving a reversible voltammetric peak in acetone with E<sub>p</sub>=+0.09 V （vs. Ag/AgCl）, which agreed well with that reported by ZHU Tian-pei and YU Feng-lan with E<sub>1/20</sub>=+0.10 V（vs. SCE）. This reversible peak is not interfered by other rare earths or small amounts of O<sub>2</sub> and water. The effects of trace amounts of O<sub>2</sub> and water on other rare earths in anhydrous acetone were further investigated. This note presents the
