DIN EN 14582:2016-12 EN 14582:2016 (E) 5 Introduction Sulfur and halogens (fluorine, chlorine, bromine and iodine) may be found in mat

30、erials in various forms. During the combustion of these materials, corrosive and harmful compounds may be released. The determination of sulfur and halogens by oxygen combustion may be used to assess the suitability of waste for incineration. The determination of the resultant halides and sulphate c

31、an be achieved by many different techniques, e.g. using atomic emission spectrometry, titrimetry or ion chromatography. Validation data of these different techniques are given in Annex A (informative). Another method, oxygen flask combustion by Schoeniger, did not pass the method validation due to l

32、ack of participants. This method is described in Annex B (informative). Anyone dealing with waste and sludge analysis should be aware of the typical risks of that kind of material irrespective of the parameter to be determined. Waste and sludge samples may contain hazardous (e.g. toxic, reactive, fl

33、ammable, infectious) substances, which can be liable to biological and/or chemical reaction. Consequently these samples should be handled with special care. Gases which may be produced by microbiological or chemical activity are potentially flammable and will pressurize sealed containers. Bursting b

34、ottles are likely to result in hazardous shrapnel, dust and/or aerosol. National regulations should be followed with respect to all hazards associated with this method. DIN EN 14582:2016-12 EN 14582:2016 (E) 6 1 Scope This standard specifies a combustion method for the determination of halogen and s

35、ulfur contents in materials by combustion in a closed system containing oxygen (calorimetric bomb), and the subsequent analysis of the combustion product using different analytical techniques. This method is applicable to solid, pasty and liquid samples containing more than 0,025 g/kg of halogen and

36、/or 0,025 g/kg of sulfur content. The limit of detection depends on the element, the matrix and the determination technique used. Insoluble halides and sulphate present in the sample or produced during the combustion step are not completely determined by these methods. 2 Normative references The fol

37、lowing documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies.

39、finitions For the purposes of this document, the following terms and definitions apply. NOTE Be aware that the above definitions are valid for this empirical EN only and do not comply with scientific definitions of sulfur and halogen content. 3.1 sulfur content sum of sulfur contained as organic and

40、 inorganic compounds that can be converted to sulphate by combustion and then absorbed or dissolved in an aqueous solution 3.2 halogen content sum of halogens contained as organic and inorganic compounds that can be converted to halides (fluoride, chloride, bromide, iodide) by combustion and then ab

41、sorbed or dissolved in an aqueous solution 4 Principle The sample is oxidized by combustion in a closed system (a bomb containing oxygen under pressure). Halogenated and sulfur containing compounds are converted to fluoride, chloride, bromide, iodide and sulphate, which are absorbed and/or dissolved

42、 in an absorption solution. Several methods may be used for the determination of halides and sulphate concentrations in the absorption solution. The method may be used for samples that burn with difficulty, which involves the use of a combustion enhancer. DIN EN 14582:2016-12 EN 14582:2016 (E) 7 5 I

43、nterferences There are no interferences in the combustion step described in this standard but interferences may occur during the subsequent determination of sulphate and halides (see corresponding standards). Insoluble halides and sulphate present in the sample or produced during the combustion step

44、 are not completely determined by these methods. The choice of absorption solutions may introduce interferences depending on the analytical technique used. 6 Hazards Hydrogen peroxide is very caustic; potassium and sodium hydroxide are corrosive and hydrazine hydrate is harmful, toxic and carcinogen

45、ic. Thus the operator shall wear goggles and gloves and shall work under a fume hood when handling this reagent. As this method uses a gas (oxygen) at a high temperature and a high pressure, precautions shall be taken by the operator. 7 Reagents and control mixtures 7.1 Reagents 7.1.1 General All re

46、agents shall be at least of analytical grade and suitable for their specific purposes. Particularly, they shall be free of sulfur and halogens. The reagents correspond to the chemical compounds used for the preparation of the absorption solutions; they are not all necessary depending on the choice o

47、f the solutions made by the laboratory for the determination of halides and sulfur (see Annex C). 7.1.2 Water of grade 1 as specified in EN ISO 3696. 7.1.3 Sodium hydroxide (NaOH) or potassium hydroxide (KOH) pellets. 7.1.4 Sodium bicarbonate NaHCO3and sodium carbonate Na2CO3. 7.1.5 Hydrogen peroxid

48、e (about 30 %) (H2O2). 7.1.6 Hydrazine hydrate (H2N-NH2H2O), reagent grade about 50 % 60 %. 7.1.7 Ascorbic acid (C6H8O6). 7.1.8 Oxygen, free of combustible material, available at a pressure of 3 MPa to 4 MPa (30 atm to 40 atm) (e.g. medical grade). 7.1.9 Combustion enhancer (e.g. paraffin). 7.1.10 A
