N.A.Grigorieva等研究了在有电子供体添加剂(L)存在条件下,用溶解在正壬烷和煤油中的二(2,4,4-三甲基戊基)二硫代次膦酸(HR)从硫酸中萃取钴。所用添加剂包括:三辛胺(TOA),三烷基胺(TAA)、三辛基氧膦(TOPO)、三烷基氧膦(TAPO)、磷酸三丁酯(TBP)和正辛醇(n-octanol)。首先采用电子能谱法研究了钴提取物(CoR2)与各种添加剂之间的相互作用。结果表明,钴的氧化 NAGrigorieva et al. Studied the effect of bis (2,4,4-trimethylpentyl) dithiophosphinic acid (HR) dissolved in n-nonane and kerosene (HR) in the presence of electron donor additive Extraction of cobalt from sulfuric acid. The additives used include: TOA, TAA, TOPO, TAPO, TBP and n-octanol (n- octanol). First, the interaction between CoR2 and various additives was studied by electron spectroscopy. The results show that the oxidation of cobalt
