30、ns are used in industrial, commercial and domestic fields, and can enter a water body via waste water and may consequently contaminate drinking water. Furthermore, they can originate from the use of chlorine as an oxidizing agent in water and waste-water treatment. They also can be introduced by ina

31、ppropriate handling. In addition, they can be formed by decomposition of higher molecular mass organohalogen derivatives. In uncontaminated ground water and rain water, the concentrations of halogenated hydrocarbons are generally below 0,l pg/I. In surface water they may be higher, depending on the

32、origin and quality of the water. In untreated waste water the concentrations may reach saturation of the aqueous phase. In general, the solubility of these compounds in organic solvents and in fatty material exceeds their solubility in water. Page 4 EN IS0 10301 : 1997 Compound Section 1 : General Q

Page 6 EN IS0 10301 : 1997 1.3 Definition For the purposes of this International Standard, the following definition applies 1.3.1 highly volatile halogenated hydrocarbons: Fluorinated, chlorinated, brominated and/or iodinated mainly nonaromatic hydrocarbons

44、composed of one to six atoms of car bon. NOTE Their boiling points generally fall within the range of 20 “C to 220 “C at atmospheric pressure (see annex A). Page 7 EN IS0 10301 : 1997 Section 2 : Liquid/liquid extraction and analysis by gas chromatography 2.1 Principle The highly volatile halogenate

45、d hydrocarbons are extracted into an organic solvent. The solution is then analysed by gas chromatography with an electron-capture detector or any other suitable detector. 2.2 Interferences Interferences can be due to the sampling procedure, vials and stoppers, solvents, gases, organic compounds in

46、the laboratory atmosphere and contamination from the autosampler. Procedures for minimizing contamination are given in 2.5 and 2.6. 2.3 Reagents All reagents shall be of sufficient purity so as to not give rise to significant interfering peaks in the gas chromatogram of the solvent extract. The puri

47、ty of reagents shall be verified by a suitable procedure, for example, by blank determinations (see 2.6.4). Reagents can become contaminated by contact with air and other materials, particularly plastics, or by degradation caused by the action of light. Store all reagents in the dark in tightly seal

48、ed all-glass containers or other suitable vessels. 2.3.1 Water for the preparation of calibration solutions and blank The quality of the water used shall be determined. For example, use the following procedure as a suitable preparation method : Place water in a bottle with a conical shoulder, nomina

49、l capacity 2 litres, fitted with a ground-glass stopper, pretreated according to 2.4.2. Determine the content of the highly volatile halogenated hydrocarbons in this water If the water is contaminated, purify as follows : - position a glass delivery tube with a sintered glass distributor a few millimetres above the bottom of the bottle ; - heat the water to approximately 60 “C ; - pass a stream of clean nitrogen (approximately 150-200 ml/min) through the water for 1 h via the bubbler. Let the water cool to room temperature and stopper the bottle ; - store the wa
