Method: Water quality - Determination of selected alkylphenols - Part 1: Method for non-filtered samples using liquid- liquid extraction and gas chromatography with mass selective detection. 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 in a concentration range from 0,1 ?µg/l to 50 ?µg/l. Higher concentrations may be measured after appropriate dilution of the sample.
