Abstract
Studies on the extraction of carbolic acid (phenol) at different pHs by trioctyl methylammonium chloride (TOMAC) diluted in octane, decan, octan-1-ol, and decan-1-ol are reported. Experimental results of batch extraction experiments are calculated and reported for distribution coefficients (KD), loading factors (Z), and extraction efficiency (E). All measurements were carried out at 298.15 K. The maximum removal of phenol was observed to be 88.679% at pH = 5 for octan-1-ol. The results of the liquid–liquid equilibrium measurements were correlated with a linear solvation energy relationship (LSER) model, which takes into account physical interactions. The remaining parameters were fitted to the experimental results. Experimental results for the liquid–liquid equilibrium were compared to the model. The LSER model was applied to correlate experimental values.
