稀土、苯氧乙酸、1,10-邻菲罗啉配合物的合成及抑菌

Synthesis and Fungistatic Effect of Ternary Complexes Rare-earths with Phenoxyacetic Acid and 1,10-Phenanthroline

在乙醇水溶液中合成了六种苯氧乙酸(HPOA)-邻菲罗啉(Phen)-稀土三元固体配合物,采用元素分析,红外光谱,差热热重等测试方法进行表征,确定配合物的化学组成为RE(POA)3Phen(RE=La3+,Pr3+,Nd3+,Sm3+,Gd3+,Dy3+)。研究了稀土配合物的抑菌活性,结果表明稀土三元配合物的抑菌效果较单独的稀土氯化物、邻菲罗啉和苯氧乙酸好。

Six solid ternary rare earth complexes with phenoxyacetic acid （HPOA） and 1,10 -Phenanthroline （Phen） were synthesized in ethyl alcohol absolute. Their composition and properties were characterized by the elemental analysis, IR and TG - DAT. These complexes had the same composition of RE （POA） 3 Phen （ RE = La3 ＋ , Pr3 ＋ , Nd3 ＋ , Sm3＋ , Gd3 ＋ , Dy3＋ ）. The fungistatie effects of complexes were also studied. Results from fungistatic testing indicated that all these complexes had fungistatic ability on molds.
