Partition of non-ionic organics in hybrid-hydrotalcite/water systems

Sorption of toluene and nitrobenzene by dodecyl sulfate intercalated-hydrotalcite was studied as a function of solute concentration. The correlation between the derived partition coefficients and the solubilities of the aromatic solutes in water indicates that the main sorption mechanism is partitio...
