Preparation and hypersensitive transition for the ternary coordination compounds of lanthanide ions(Nd3+,Ho3+,Er3+)with salicylic acid(HSAL)and diantipyryl-methane(DAM)
【摘要】 用光度法研究了乙醇-水溶液中镧系离子(Nd3+、Ho3+、Er3+)与水杨酸(HSal)及二安替吡啉甲烷(DAM)三元配合物的超灵敏跃迁,测得三元配合物的组成比为Ln3+:HSal:DAM=1:3:1.制备了固态钕三元配合物,并用元素分析、红外和紫外光谱以及热谱进行了表征.
【Abstract】 The ternary coordination compounds of lanthanide ions(Nd3+,Ho3+, Er3+) with Hsal and DAM in water-ethnolic solution were.studied by using spec.trophotometry.The component ratio of the ternary coordination compounds in solution is Ln3+:Hsal:DAM=1:3:1.The corresponding coordination compound of neodymium is prepared in solid state and characterized with elemental analysis,ultraviolet and infrared spectra,as well as thermogravimetry. Its.composition is Nd(C7H3O5)3.C23H24N4O2·2H2O.
