标准范围

ISO 18857-1:2005规定了饮用水、地下水和地表水未过滤样品中4-壬基酚（异构体混合物）和4-（1,1,3,3-四甲基丁基）苯酚的测定方法。该方法适用于4-（1,1,3,3-四甲基丁基）苯酚的浓度范围为0005微克/升至0.2微克/升，4-壬基酚（异构体混合物）的浓度范围为0.02微克/升至0.2微克/升。根据基质的不同，该方法也适用于含有浓度范围为0.1微克/升至50微克/升的分析化合物的废水。在适当稀释样品后，可以测量更高的浓度。

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.
