摘要
用循环伏安法研究了硝酸铕与氮杂冠醚配合物在不同质子惰性溶剂中的电化学行为结果表明。
Electrochemical behavior of complex of europium nitrate with diaza -- 18 -- crown -- 6 have been investigated in aprotic solvents by means of cyclic voltammetry. Significant effect of solvent and structure of macrocyclic ethers on the reduction processes is found. Coordination of diaza - 18- in crown -- 6 in weak bonding solvents is favorable to stabilize the divalent europium, so that the half -- wave potentials Eu3 + for reduction reaction shifts 200~ 300 my to anode. Farthermore, the effect of the scan rate ad the concentrations of electroactive species on the curves of CV are discussed.
