Anionic and Nonionic Detergent Determination by Flameless Atomic Absorption Spectrophotometry

Abstract

Procedures for the determination of anionic and nonionic detergents in natural waters are described. Flameless atomic absorption spectrophotometry enables reduction of the sample volume and of the number of steps in the procedure. Sensitivities are better than 10 μg.1^?1 and relative standard deviations are of the order of 5%.
