Description (English):

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.

Abstract

Overview

EN ISO 18857-1:2006 (ISO 18857-1:2005) is a CEN-endorsed international standard that specifies a validated laboratory method for the determination of selected alkylphenols in non-filtered water samples. It covers analysis of 4-nonylphenol (technical mixture of isomers) and 4-(1,1,3,3-tetramethylbutyl)phenol using liquid–liquid extraction and gas chromatography with mass selective detection (GC–MS). Typical sample matrices include drinking water, ground water, surface water and-depending on matrix-wastewater.

Key topics and technical requirements

Analytes and scope
- 4-(1,1,3,3-tetramethylbutyl)phenol: applicable range 0.005 µg/L to 0.2 µg/L.
- 4-nonylphenol (mixture): applicable range 0.02 µg/L to 0.2 µg/L.
- Wastewater applicability: typically 0.1 µg/L to 50 µg/L (higher concentrations by dilution).
Analytical principle
- Acidify sample and extract alkylphenols into toluene by liquid–liquid extraction.
- Optional silica cleanup of the extract.
- Separation on capillary GC and identification/quantification by mass spectrometry (selected m/z).
- Quantification uses an internal standard and daily determination of response factors.
Reagents and quality control
- Use high-purity solvents (toluene, hexane, acetone) and grade‑1 water.
- Internal standards and calibration standards (4-nonylphenol, 4‑(1,1,3,3‑tetramethylbutyl)phenol) are specified.
- Regular blank checks and recovery tests; monitor for contamination from plastics and labware.
Apparatus and sample handling
- Typical extraction volume: ~1 000 mL (smaller volumes possible).
- Clean glassware, appropriate separators, drying columns and GC–MS with data acquisition capable of selected-ion quantification.

Applications and who uses it

Environmental and public health laboratories performing regulatory monitoring of water quality for endocrine-disrupting alkylphenols.
Water utilities and environmental consultancies testing drinking water, groundwater and surface waters for contamination.
Wastewater treatment and research labs assessing effluent concentrations and treatment efficiency (with adapted concentration ranges).
Regulatory agencies implementing compliance testing against environmental quality standards.

Practical value

Provides a standardized, reproducible GC–MS method for trace-level detection of alkylphenols-critical for assessing endocrine disruptor exposure risks.
Enables inter-laboratory comparability and supports regulatory compliance and environmental monitoring programs.

Related standards
