Water quality — Determination of selected alkylphenols — Part 2: Gas chromatographic-mass spectrometric determination of alkylophenols, their ethoxylates and bisphenol A in non-filtered samples following solid-phase extraction derivatisation

Abstract

This part of ISO 18857 specifies a gas chromatographic-mass spectrometric (GC-MS) determination of
selected alkylphenols, their ethoxylates and bisphenol A in non-filtered samples of drinking, ground, surface,
and waste waters following solid-phase extraction and derivatisation.
The lower limit of the working range depends on the matrix, on the specific compound to be analysed and on
the sensitivity of the mass spectrometric detection unit. The method is applicable in a working range from
0,005 ?g/l to 0,2 ?g/l for 4-(1,1,3,3-tetramethylbutyl)phenol (OP), and its mono- (OP1EO) and diethoxylate
(OP2EO), from 0,03 ?g/l to 0,2 ?g/l for 4-nonylphenol (mixture of isomers) (NP), and its mono- (NP1EO) and
diethoxylate (NP2EO), and from 0,05 ?g/l to 0,2 ?g/l for bisphenol A (BPA).
Depending on the matrix, the method is also applicable to waste water in a working range from 0,1 ?g/l to
50 ?g/l for OP, OP1EO, OP2EO and BPA, and from 0,5 ?g/l to 50 ?g/l for NP, NP1EO and NP2EO. The
working ranges are based on experimental work carried out in ruggedness testing. Water samples containing
suspended matter at concentrations of more than 500 mg/l and waste water samples are extracted by passing
a 100 ml sample through the cartridge.
