This document specifies a method for determination of organochlorine pesticides, polychlorinated biphenyls and chlorobenzene in water after liquid-liquid extraction and gas chromatography and mass spectrometric detection. This method is applicable to drinking water, ground water, surface water and waste water whit in a mass concentration range from 5 ng/l.
The standard applies for definitions of the essential terms in the field of the collection, transport, treatment, discharge (and reuse) of wastewater and in the field of sludge treatment, utilization and disposal.For the preparation or revision of all standards within the field of wastewater this document provides the general basis for the terms and definitions.
This International Standard specifies a method for the determination of phthalates in water after solid phaseextraction and gas chromatography/mass spectrometry.This method is applicable to the determination of phthalates (see Table 1) in ground water, surface water,wastewater and drinking water in mass concentrations ranging from above 0,02 μg/I up to 0,150μg/I,depending on the individual substance and the value of the blank.The applicability of this method to other phthalates not specified in Table 1 is not excluded, but it is necessaryto determine its applicability in each case (see Annex A for the list of phthalates).General remarks concerning the recovery and use of internal standards is given in Annex B.
ISO 18856:2004 specifies a method for the determination of phthalates in water after solid phase extraction and gas chromatography/mass spectrometry.This method is applicable to the determination of phthalates in ground water, surface water, wastewater and drinking water in mass concentrations ranging from above 0,02 microgram per litre up to 0,150 microgram per litre, depending on the individual substance and the value of the blank.The applicability of this method to other phthalates not specified is not excluded, but it is necessary to determine its applicability in each case.
