ABSTRACT
The aim of this study is to investigate the extraction of citric acid and maleic acid from their aqueous solutions using different solvent-extractant mixtures in order to find the most effective composition for the extraction. Citric and maleic acids are chosen as the carboxylic acids due to their commercial worth in the industrial processes. Carboxylic acids are recovered from their aqueous solutions by reactive extraction, a promising liquid-liquid extraction technique, using trioctylphosphineoxide (TOPO), and secondary amine called dioctylamine (DOA). TOPO has been chosen as an extractant since it has low water solubility, high stability and it is more environmentally friendly than the amine type extractants. Among the other amine extractans used in reactive extraction processes, there is a lack of study about the extraction of these acids with DOA in the literature. Extractants were dissolved in nine different solvents (butanol, decanol, octanol, isoamylalcohol, octane, decane, methylisobutylketone, diisobutylketone) having different chemical structures. All experiments were carried out at 298,15 K. Comparison of the results were made using the distribution coefficient (D), loading factor (Z), and the extraction yield (%E). It has been observed that considerable amount of citric acid and maleic acid extraction achieved using DOA (in the range of %13.95 99.19 and %31.94 99.41 according to the diluent used for citric acid and maleic acid respectively) compared to the that of achieved with TOPO (in the range of %0.81 67.12 and %16,.25 89.33 according to the diluent used for citric acid and maleic acid respectively).
