摘要
研究了碱性硼氢化钠 (SBH)和酸性硫脲 (Tu)从磷酸三丁酯 (TBP) -十六烷基三甲基溴化铵 (CTMAB) -正十二烷载金 (C1 2 H2 6)有机相中反萃金 ,考察了平衡时间、pH值、反萃剂用量 (浓度 )、温度等因素对反萃率的影响 ,结果表明 ,SBH和Tu对Au均有较高反萃率 ,可顺利实现Au的反萃。
Stripping gold from TBP-CTMAB-C 12 H 26 gold-loaded organic phase by alkaline SBH and acid Tu have been investigated respectively.The effect of several variables,such as stripping time,temperature,pH,HCl concentration,dosage of SBH and Tu concentration are discussed.The stripping isotherm has also been protracted.The results show that the SBH and Tu can strip gold favorably from TBP-CTMAB-C 12 H 26 gold loaded organic phase.
