Abstract
The widespread use of detergents that exhibit little or no degradation in surface waters has produced many problems in water supply and pollution control. Prerequisite to an evaluation of these problems and the development of remedial measures is an efficient, reliable analytical procedure for identifying synthetic detergents and measuring the concentrations present. This study was undertaken to evalute the precision and accuracy of the three most widely used procedures for detergent analysis and the degree of reagent cleanup required to remove interferences. The three methods are based on the reaction of alkyl benzene sulfonate with methylene blue dye, which forms a chloroform-soluble blue complex which is measured spectrophotometrically. The methods differ in the degree of reagent cleanup provided.
