BS EN 14582:2016EN 14582:2016 (E) 5 Introduction Sulfur and ha

21、logens (fluorine, chlorine, bromine and iodine) may be found in materials 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 inci

22、neration. The determination of the resultant halides and sulphate can 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 co

23、mbustion by Schoeniger, did not pass the method validation due to lack 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

24、 and sludge samples may contain hazardous (e.g. toxic, reactive, flammable, 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 pote

25、ntially flammable and will pressurize sealed containers. Bursting bottles 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. BS EN 14582:2016EN 14582:2016 (E) 6 1 Scope This standard specif

26、ies a combustion method for the determination of halogen and sulfur 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

27、 liquid samples containing more than 0,025 g/kg of halogen and/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 complete

28、ly determined by these methods. 2 Normative references The following 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. For undated references, the latest edition of the referenc

29、ed document (including any amendments) applies.

30、use - Specification and test methods (ISO 3696) 3 Terms and definitions 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 cont

31、ent. 3.1 sulfur content sum of sulfur contained as organic and 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 (

32、fluoride, chloride, bromide, iodide) by combustion and then absorbed 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, bro

33、mide, iodide and sulphate, which are absorbed and/or dissolved 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 com

34、bustion enhancer. BS EN 14582:2016EN 14582:2016 (E) 7 5 Interferences 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 pre

35、sent in the sample or produced during the combustion step 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 corrosi

36、ve and hydrazine hydrate is harmful, toxic and carcinogenic. 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 Reagen

37、ts and control mixtures 7.1 Reagents 7.1.1 General All reagents 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 soluti

38、ons; they are not all necessary depending on the choice of 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

39、NaHCO3and sodium carbonate Na2CO3. 7.1.5 Hydrogen peroxide (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 gr

40、ade). 7.1.9 Combustion enhancer (e.g. paraffin). 7.1.10 Aluminium oxide, Al2O3, neutral, particle size 200 m, pre-heated to 600 C. 7.1.11 Gelatine or aceto-butyrate capsules. 7.2 Control mixtures Select a certified reference material (CRM) or create an appropriate control mixture by choosing the con

41、trol substances in combination so all elements that shall be determined in the samples are BS EN 14582:2016EN 14582:2016 (E) 8 represented. The amount of halogen and sulfur contents shall be in the same range of the element contents of the samples and approximately in the middle of the working range

42、 of the determination techniques. If necessary, dilute with cellulose or aluminium oxide to get a suitable element content. The mixture of the control substances and the cellulose or aluminium oxide needs to be homogenized, e.g. using a pestle with mortar or ball mill. Table D.1 lists examples of co

43、ntrol substances that give complete (90 % to 110 %) recoveries of halogen and sulfur. NOTE Combined combustion of iodine and sulfur may interact to improve the reduction of iodine to iodide and the oxidation of sulfur to sulphate. If the actual samples only contain one of the elements, a combined co

44、ntrol mixture may give false assurance of the method capacity. Examples of composition for a control mixture to determine fluorine, chlorine and sulfur (control mixture 1) and another control mixture for bromine and iodine (control mixture 2) are detailed in Table 1. Table 1 Examples of control mixt

47、r should be carried out within seven days after sampling. If this is not possible, the samples should be further preserved by e.g. freezing, if possible, to minimize biodegradation and loss of volatile halogenated and sulfur compounds. The test sample is prepared according to EN 15002. For solid mat

48、erials, the particle size should be less than 200 m. During preparation of the test sample, the use of halogenated polymers, e.g. PVC gloves, should be avoided. Drying the laboratory sample may be carried out for homogenization purposes if the sample, according to the accuracy of the method, contain

49、s only negligible amounts of halogen and sulfur compounds volatile at the temperature intended for the drying process. Dry matter is determined according to EN 14346 on a separate sub sample (the result will be used for calculation). Heterogeneous moist or paste like samples may be mixed with aluminium oxide (7.1.10) until granular material is obtained and then reduced to a granular powder, preferably with a particle size less than 200 m. In this case, the ratio of aluminium oxide to sample should be incorporated into the calculation of the halogen and sulfur con
