Water quality - Determination of selected alkylphenols - Part 1: Method for non-filtered samples using liquid-liquid extraction and gas chromatography with mass selective detection (ISO 18857-1:2005)

ISO 18857-1:2005 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 micrograms per litre to 0,2 micrograms per litre for 4-(1,1,3,3-tetramethylbutyl)phenol and from 0,02 micrograms per litre to 0,2 micrograms per litre 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 micrograms per litre to 50 micrograms per litre. Higher concentrations can be measured after appropriate dilution of the sample.

L'ISO 18857-1:2005 spécifie une méthode de dosage du 4-nonylphénol (mélange d'isomères) et du 4-(1,1,3,3-tétraméthylbutyl)phénol dans des échantillons non filtrés d'eaux potables, d'eaux souterraines et d'eaux de surface. La méthode est applicable dans une plage de concentrations comprise entre 0,005 microgramme par litre et 0,2 microgramme par litre pour le 4-(1,1,3,3-tétraméthylbutyl)phénol et entre 0,02 microgramme par litre et 0,2 microgramme par litre pour le 4-nonylphénol (mélange d'isomères). Selon la matrice, cette méthode est également applicable aux eaux résiduaires dans une plage de concentrations de 0,1 microgramme par litre à 50 microgrammes par litre. De plus fortes concentrations peuvent être mesurées après dilution appropriée de l'échantillon.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 18857-1 was prepared by Technical Committee ISO/TC 147, Water quality, Subcommittee SC 2, Physical,
chemical and biochemical methods.
ISO 18857 consists of the following parts, under the general title Water quality — Determination of selected
alkylphenols:
 Part 1: Method for non-filtered samples using liquid-liquid extraction and gas chromatography with mass
selective detection
 Part 2: Method for filtered samples using solid phase extraction and gas chromatography with mass
selective detection

WARNING — Persons using this International Standard should be familiar with normal laboratory
practice. This International Standard does not purport to address all of the safety problems, if any,
associated with its use. It is the responsibility of the user to establish appropriate safety and health
practices and to ensure compliance with any national regulatory conditions.
IMPORTANT — It is absolutely essential that tests conducted in accordance with this part of ISO 18857
be carried out by suitably qualified staff.
1 Scope
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 µg/l to 0,2 µg/l for
4-(1,1,3,3-tetramethylbutyl)phenol and from 0,02 µg/l to 0,2 µg/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 µg/l to 50 µg/l. Higher concentrations can be measured after appropriate
dilution of the sample.

3 Principle
The compounds 4-(1,1,3,3-tetramethylbutyl)phenol and 4-nonylphenol (mixture of isomers) are extracted from
the acidified water sample with toluene. The extract is cleaned, if necessary, with silica and the alkylphenols
are separated by gas chromatography using capillary columns. The alkylphenols are identified by mass
spectrometry and quantified using an internal standard over the total procedure. The response factor using
4-(1,1,3,3-tetramethylbutyl)phenol and a technical mixture of isomers of 4-nonylphenol is determined daily.
