DIMENSIONAL ANALYSIS OF TWENTY-EIGHT DETERGENCY SYSTEMS.
Abstract
Replacement of micellar solubilization by surfactant concentration as one of the six significant variables of the detergency process (1) resulted in a more useful set of dimensionless products. The change affords easier and more accurate experimental control over the products, and an improved detergency diagram. The latter, representing a log-log function of two of the dimensionless products at parameter values of the third, consists of a series of parallel lines with a negative slope of approximately 45 degrees. The dimensional analysis was validated by twenty-five soilsurfactant systems formed from six different types of soil and seven surfactants including two types of anionics and two types of nonionics. Non-validation of the products of a dimensional analysis in which the dimensions of detergency were changed to those of energy, or ML2/T2 (M=mass, L= length, T= time), tended to confirm the simplified model of the process and dimensions (ML) previously postulated (1).
