Rapid automated determination of constants of solubility product and critical micelle concentrations by the flow-rate gradient technique.
Several straightforward, rapid and automated methods for the determination of the constant of solubility product of various inorganic salts and hydroxides and the critical micelle concentrations of both anionic and cationic surfactants are reported. The underlying methodology relies on the establishment of flow-rate gradients in completely continuous flow systems including a conductometric or potentiometric detector. The results obtained are quite consistent with those reported in the chemical literature.
