1、 畢業(yè)設(shè)計（論文） 畢業(yè)設(shè)計（論文）題 目： 目： 鑭與對苯二甲酸鄰啡咯啉二元 鑭與對苯二甲酸鄰啡咯啉二元 三元配合物的合成與表征 三元配合物的合成與表征 AbstractThe rare earth is one kind has the special structure and the nature element, the rare-e

2、arth element not only massively uses in the industry, moreover also has the widespread application in the agriculture and the medicine domain. According to the preparation coordination bond theory, this kind of element i

3、s extremely easy with some ligands to form the stable preparation. As has the outstanding light, the electricity, magnetism and so on special function。Therefore the rare earth material's application has involved to t

4、he biology, the agriculture, the medicine and the military and so on each domain。Already had many research take the benzoic acid and the derivative as the ligand, but are actually few take the phthalic acid as the ligand

5、, moreover the predecessor mainly concentrates to the rare earth research in has metals and so on very good on fluorescence you terbium, are relatively few regarding the lanthanum research。In view of this, this researc

6、h design synthesizes a series of new lanthanum and the dicarboxylic acid and l,10- neighbour Philippines dual three Yuan preparations. The actual content is as follows: 1.The present paper take the dicarboxylic acid as

7、the first ligand, hui lin synthesizes 7 kind of lanthanum take the l,10- neighbour Philippines as the second ligand dual and three Yuan preparations, through the ultimate analysis (C, N, H and the EDTA coordinate titrate

8、, determines the preparation initially the composition2.With methods and so on IR, TG-DTG have carried on the attribute and the nature research to the lanthanum preparation. In preparation, La (Ⅲ) has formed the stable c

9、hemical bond with the carboxyl group oxygen atom and the neutral ligand's nitrogen atom, these preparations have the good thermostability 3.The present paper prime task concentrates in: (1) studied the different reso
