Effect of Diluents on the Extraction of Oxalic Acid by Trialkylphosphine Oxide
摘要
In liquid-liquid solvent extraction processes, diluents have a strong influence on the extraction mechanism and efficiency. In this study, benzene, cyclohexane, trichloromethane, carbon tetrachloride, methyl isobutyl ketone (MIBK), butyl acetate, and 1-octanol were used as diluents in the extraction of oxalic acid by trialkylphos-phine oxide (TRPO). The effects of extractant concentration, initial concentration of oxalic acid and diluent type on the extraction equilibrium partition coefficient are analyzed. The sequence of the extraction ability by different diluents is MIBK butyl acetate cyclohexane=benzene carbon tetrachloride 1-octanol trichloromethane. Extraction mechanism was analyzed and extraction model parameters were evaluated.
