ISO 18857-1-2005 水质.选定的烷基苯酚测定.第1部分:利用液-液萃取法和有选择性质量检测的气相色谱法的无过滤样品法
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 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.
