The diluent solution of glyoxylic acid and oxalic acid was used as the separation object.TOA (in n-octanol) was used as the solvent. The extraction characteristics of single acid and two-acid solution were studied,and the influence of pH and the concentration of complexing agent on the distribution coefficients were measured. The suitable mathematic models were proposed to describe the relationship between TOA and carboxylic acid based on assumed extraction reaction in organic phase.
