Abstract
The use of surfactants in flame atomic absorption has been reported previously (1–7). Surfactants in dilute solutions below their critical micellar concentration (CMC) act as strong electrolytes. Above their CMC they exhibit unique solvent property changes such as apparent molar volumes, density, specific heat, electrical conductance, electromotive force, surface tension, vapor pressure, microfluidity or viscosity, and the temperature coefficient of solubility (9). It was the purpose of these studies to ascertain whether or not these changes in the solvent properties of water would effect atomic absorption signals. A review of the literature on this subject results in apparent inconsistencies in the fmal results and the theories that explain this phenomena. In the original papers some confusion might have resulted because the enhancement of signals had been reported three different ways. For ease in comparison these values have been recalculated as ratios of the signal studied compared to their aqueous solutions. For example a value of 1.10 could have previously been reported as a 10% enhancement or 110% of the aqueous signal.
