N,N-二甲基-3-氧杂-戊酰胺酸与Np(Ⅳ),Pu(Ⅳ)配合物稳定常数的测定

应用溶剂萃取法研究了N，N-二甲基-3-氧杂-戊酰胺酸(DOGA)与Np(Ⅳ)，Pu(Ⅳ)的配位行为。研究结果表明，DOGA与Np(Ⅳ)，Pu(Ⅳ)在25℃可以形成比较稳定的配合物，配合物的逐级累积稳定常数分别为：Pu(DOGA)3^ ：1gβ1=6．52，1gβ2=9．14，1gβ3=15．77；Np(DOGA)3^ ：1gβ1=6．95，1gβ2=10．435，1gβ3=14．93。     

Structure of Complexes of Lanthanides with N,N′-Dimethyl-3-Oxa-Glutaramic Acid

With the development of nuclear energy, how todispose of the nuclear wastes especially high level liq uid wastes (HLLW) is the world′s subject. One strat egy for reducing the main long term hazard of radioac tive waste is to separate actinides from high level liq uid waste (HLLW) and transmute them into short lived or stable nuclides by nuclear reactions in nuclearreactors or accelerator driven transmutation systems.For this subject, many countries have brought forwardmany p…

荷境文心

荷境,即面对荷花的心境,是一种不为物扰、自由自在的状态,是人们本色和真实的体验。由此,心灵会因荷花而鲜和起来、舒畅起来、充实起来,也就是如如实实地接纳真实的自己。古语日：“石蕴玉而山辉,水含珠而川媚。”在花草文化中,荷花就是一块包裹着美玉的璞石,荷池、荷塘就是一泓蕴含着明珠的清水。攻璞而取玉,探水而觅珠,现代的人们可以从荷境中获得不少精神的愉悦和智慧的启迪。     

长沙窑尚待解决的几个问题之我见

长沙窑是中国南方的一个瓷窑，是唐代外销瓷的一个重要的生产基地。它首创了绚丽的高温釉下彩彩绘新工艺，并熟练地掌握了烧制高温铜红釉的技术。长沙窑还开创了别具一格以花鸟画为题材和书写诗文装饰瓷器的新局面，使高雅的诗画艺术能进入平常百姓家，因而在中国陶瓷发展史上有不可替代的重要地位。同时，它融合中西文化特色的产品大量销往海外，在中外经济、文化交流史上写下了光辉的一页。     

Structure of Complexes of Lanthanides with N, N＇-Dimethyl-3-Oxa-Glutaramic Acid

A new stripping agent N, N-dimetbyl-3-oxa-glutaramic Acid (DOGA) was used in TRPO process to simplify the TRPO process. The structures of the complexes of the DOGA with Eu(Ⅲ), Nd(Ⅲ), La(Ⅲ) were characterized with extended X-ray absorption fine structure spectroscopy (EXAFS), infrared spectra (IR) and mass spectra (MS). The molecular formula of the complexes of Eu( Ⅲ ) and Nd( Ⅲ ) is deduced to be M(DOGA)3, and only La( Ⅲ ) can form the complex HM(DOGA)4 under condition of high consistency of the DOGA. The coordination number of Ln( Ⅲ ) in the complexes is 8, and all of coordinated donor atoms are O atoms. For Eu( Ⅲ ), Nd( Ⅲ ), the coordination numbers of O atom in the first coordination shell is 6 and the average coordination bond lengths of Ln - O are 0.240 nm, 0.244 nm respectively,while the numbers of the second O shell are 2.4, and the average coordination bond lengths of Ln - O are 0.260 nm,0. 262 nm. For La( Ⅲ ), the coordination numbers of O atom in the first coordination shell is 6 and the average coordination bond lengths of La - O are 0.258nm, while the number of O atom in the second coordination shell is 4.4, and the average coordination bond length of La - O is 0.28 nm. The results of IR and MS show that there is no water coordinating with Ln( Ⅲ ) in the complexes.
