在Y型分子筛中Co^（2＋）、Ni^（2＋）配合物的合成及其应用研究

STUDY ON THE SYNTHESIS AND THE APPLICATION OF Co￣(2+),Ni￣(2+) COMPLEXES IN Y-TYPE ZEOLITE

用气相法和液相法分别在Ｙ型分子筛的超笼中合成了Ｃｏ（２＋）、Ｎｉ（２＋）的乙二胺配合物，并用红外（ＦＴ－ＩＲ）、顺磁共振（ＥＳＲ）等方法对配合物的组成和稳定性进行了研究．ＣＯ（２＋）的单核配合物在室温下可与Ｏ２分子形成加合物，这种优先并可逆地吸附氧气的性能在氧气富集、对空气进行氧氮分离和食品保鲜等方面有广泛的用途．

Co(2+),Ni(2+)complexes with ethylenediamine were synthesized in super cages of Y-type zeolite by methods of gas-solid reaction and solid-liquid exchanging. The composition and the stability of complexes were invcstigated by IR and ESR spectroscopies. The Co(2+)complex with single core can absorb O2 and form adducts reversibly in room temperature. This property of the complex can be widely applied in oxygen concentrating, separating O2 from the air, keeping fresh for foods and so on.
