Surface active agents - Determination of chloroacetic acid (chloroacetate) in surfactants - Part 2: Ionic chromatographic method
ISO 17293-2:2014 specifies a method for the determination of monochloroacetic acid (monochloroacetate) and dichloroacetic acid (dichloroacetate) in surfactants by ion chromatographic method.
The method applies for anionic surfactants such as alkyl (phenyl) ethoxylated carboxylate (AEC) or amphoteric surfactants such as alkyl imidazoline carboxylate, alkyl dimethyl betaine, and fatty acetyl propyl dimethyl betaine.
The limit of detection (LOD) is โค0,01 ยตg/ml for monochloroacetic acid and โค0,05 ยตg/ml for dichloroacetic acid; and the limit of quantification (LOQ) is โค0,1 ยตg/ml for each standard (using a standard solution).
The LOD, at 1 g of sample weight, is โค1 mg/kg for monochloroacetic acid and โค5 mg/kg for dichloroacetic acid; and the LOQ is โค10 mg/kg for each acid.
