仲碳伯胺萃取铈(Ⅳ)机理的~1H,^(15)N核磁共振谱研究

~1H and ^(15)N-Nuclear Magnetic Resonance Studies on the Extraction Mechanism of Cerium(Ⅳ)by Primary Amine N_(1923)

仲碳伯胺N_(1923)萃取铈(Ⅳ)的~1H,^(15)N-NMR研究表明,在萃取铈(Ⅳ)时也同时萃取H_2O和H_2SO_4进入有机相,当铈(Ⅳ)浓度较高时,铈(Ⅳ)与N_(1923)生成配合物。

~1H and ^(15)N-nuclear magnetic resonance are used to study on the extraction mechanism of Ce(Ⅳ) by secondary carbon primary amine N_(1923). The results indicate that water and sulfuric acid are extracted into organic phase when N_(1923) extracted Ce(Ⅳ). In the extracted processes of higher concentration of Ce(Ⅳ), N_(1923) coordinats with Cerium(Ⅳ) to produce the complex.
