摘要：

The results of decay lengths of double-layer forces in sodium dodecyl sulfate (SDS) and dodecyltrimethylammonium bromide solutions were studied. The decay lengths were determined by fitting a line to the linear region of ln(force) versus separation plots, at separations greater than one decay length. It was concluded that the equilibrium constant of weak symmetrical electrolytes could be obtained from the measurement of the decay of double-layer forces.
