ABSTRACT:
A method suitable for the rapid colorimetric testing of raw water supplies, domestic sewage or industrial wastes for determining the residual presence and concentration of either anionic or cationic surfactants. An appropriate dye will react with ionic surfactant and form a chloroform-soluble, colored complex in the presence of chloroform. The color intensity of the vigorously rocked and subsequently settled chloroform layer is proportional to the concentration of the "dye-ionic surfactant complex", and can then be measured by making spectrophotometric readings of the chloroform solution at the optimum wavelength of the instrument used.
