The effects on the extraction of Vanadium(V) by N-(2-hydroxy-5-nonylbenzyl)-β,β-dihydroxyethylamine of different factors, including pH of the medium, concentration of extracting agent, temperature and solvent type, were studied. This allows the optimal extraction conditions to be determined. It is shown that extraction of Vanadium(V) takes place with high distribution coefficients and that, in the
研究了介质pH、萃取剂浓度、温度和溶剂类型等因素对N- (2-羟基-5-壬基苄基)-β,β-二羟基乙胺萃取钒(V)的影响。 . 这允许确定最佳提取条件。结果表明,钒 (V) 的萃取以高分配系数进行,并且在有机相中形成包含十钒酸盐阴离子和四个萃取剂分子的复合物。提取的钒(V)胺络合物可稳定超过1个月。
