This part of ISO 18857 specifies a method for the determination of 4-nonylphenol (mixture of isomers) and
4-(1,1,3,3-tetramethylbutyl)phenol in non-filtered samples of drinking water, ground water and surface water.
The method is applicable in a concentration range from 0,005 ug/l to 0,2 ug/l for
4-(1,1,3,3-tetramethylbutyl)phenol and from 0,02 ug/l to 0,2 ug/l for 4-nonylphenol (mixture of isomers).
Depending on the matrix, the method is also applicable to waste water containing the analyzed compounds in
the concentration range from 0,1 ug/l to 50 ug/l. Higher concentrations can be measured after appropriate
dilution of the sample.
