【摘要】 本论文进行了金属钴、镍、铜高分子配合物的合成、性质研究，并探讨了其在金属富集分离方面的应用，共包括四个部分：1.对金属高分子配合物（Macromolecular-Metal Complexes，缩写为MMC）的研究进展及应用做了文献综述。2.合成了苯乙烯/丙烯酸共聚物（PSt/AA）和相应的钴镍铜配合物(M-PSt/AA,M=Co²⁺,Ni²⁺,Cu²⁺,图a)，对共聚物和配合物进行了表征，并研究了钴镍铜离子的吸附行为。3.合成了苯乙烯/马来酸酐共聚物（SMA）及相应水解产物的钴镍铜配合物(M-SMA,M=Co²⁺,Ni²⁺,Cu²⁺,图b)，对共聚物和配合物进行了表征，并研究了钴镍铜离子的吸附行为。4.合成了对苯二甲酸的镍配位聚合物（Ni-BDC,图c）和反丁烯二酸的镍配位聚合物（Ni-FMA,图d）,并研究了对苯二甲酸和反丁烯二酸对镍离子的吸附行为。通过元素分析、红外光谱分析、差热.热重分析、原子吸收、扫描电镜等手段对以上钴镍铜配合物进行了表征。结果显示所合成的高分子配合物都具有固定的组成,难溶于大多数有机溶剂,可应用在金属富集和分离方面。相对于传统的分离技术而言,此类分离技术工艺简单、原料可循环使用,是一种新型的绿色分离技术。更多还原

【Abstract】 The synyhesis, characterization and application in the metal enrichement and separation of cobalt, nickel and copper metal macromolecular complexes have been studied in this thesis. The paper consists of four parts as follows:1. A brief review of the study of macromolecular-metal complexes （MMC） has been given.2. The synthesis, characterization of corresponding Co²⁺, Ni²⁺, Cu²⁺ macromolecular complexes（M-PSt/AA, Fig a） with series of poly styrene and acrylic acid （PSt/AA） were studied, and the adsorption behavior towards Co²⁺, Ni²⁺ and Cu²⁺ has also been determined.3. Co²⁺, Ni²⁺, Cu²⁺complexes(M-SMA, M=Co²⁺, Ni²⁺, Cu²⁺ Fig b) with corresponding hydrolyzation of poly styrene and maleic anhydride （SMA） were synthesised, and the characterization of the polymers and coordinations have been studied. The adsorption behavior towards Co²⁺, Ni²⁺ and Cu²⁺ has also been determined. 4. Nickel coordination polymer with terephthalic acid（Ni-BDC, Fig c） and fumaric acid（Ni-FMA, Fig d） have been studied, and the adsorption behavior of terephthalic acid and fumaric acid towards Ni²⁺ has been studied detailed.These Co²⁺, Ni²⁺, Cu²⁺ complexes have been studied by means of element analysis, IRspectra, thermal analysis, atomic adsorption, scanning electron microscopy.The results show that these macromolecular complexes we synthesized arestructurally specific, insoluble in most organic solvents, and they can be used in themetal enrichement and separation.The craft is simple and the raw material can be used for repeated use, and it is a newgreen separate technology comparing to the transition one.更多还原
