scope:
This International Standard specifies a method for the determination of selected individual isomers of nonylphenol in non-filtered samples of drinking water, waste water, ground water and surface water. The method is applicable in concentrations between 0,001 μg/l and 0,1 μg/l for individual isomers and from 0,01 μg/l to 0,2 μg/l for the sum of 4-nonylphenol (mixture of isomers). Depending on the matrix, the method is also applicable to waste water in concentrations between 0,1 μg/l and 50 μg/l.
