INVESTIGATION ON THE METAL DECAVANADATES COORDINATING WITH OXINE Ⅴ. SYNTHESIS, CHARACTERIZATION AND PROPERTIES OF La (Ⅲ), Cc(Ⅲ), Pr(Ⅲ), Nd(Ⅲ), Sm(Ⅲ), Eu(Ⅲ) AND Gd(Ⅲ) SALTS
【摘要】 <正> 我们曾报道过碱金属盐的合成.近来,这方面报道较多.本文研究了希土盐。实验一、合成称28克NaVO3-4H2O(分析纯)溶于500ml水中,加200ml HOx的丙酮溶液(10克/100ml),搅匀分成七份,加热70℃时,每份分别滴加50ml溶有2克希土硝酸盐水溶液,调pH=6.2~6.8之间,搅拌30分钟,分出沉淀并干燥。二、组成分析C、H和N用元素分析仪,V和希土用原子吸收光谱仪和灼烧法。见表1。
【Abstract】 The addition compounds of the rare earth metal decavanadatcs-La(Ⅲ ), Cc(Ⅲ ),Pr (Ⅲ), Nd(Ⅲ), Sm(Ⅲ), Eu(Ⅲ) and Gd(Ⅲ) salts with bxinc were prcparcd.The IR and 13C-NMR of the addition compounds were studied. The molecular formulas of the addition compounds were suggested by the means of the elemental analysis and thermo-analysis. The molecular formulas as follows:La2(HOx)10V10O28(HOx)612H0x; Sm2(HOx)8V10O28(HOx)68HOx;Ce2(CHx)10V10O28(HOx)68HOx; Eu2(HOx)12V10O28(HOx)610HOx;Pr2(HOx)10V10028(HOx)68H0x; Gd2(HOx)6V10O28(HOx)68HOx;Nd2(HOx)10V10028(HOx)610HOx;
【Key words】 oxine (HO_x); decavanadate; La(Ⅲ) Ce(Ⅲ) Pr(Ⅲ) Nd(Ⅲ) Sm(Ⅲ) Eu(Ⅲ) Gd(Ⅲ); synthesis;
