24、5410:2011 (E) 4 Introduction Accurate determination of trace element content in solid recovered fuels is important for environmental and technical reasons both in the production and combustion stage. The determination of major elements such as Al, Ca, Fe, Mg, P, K, Si, Na and Ti can be helpful to pr

25、edict the melting behaviour and slagging of the ash. After digestion of the solid recovered fuels using different methods, a number of analytical techniques can be used for the quantification of the trace element content. They include Inductively Coupled Plasma with optical or mass detection, Flame

26、Atomic Spectroscopy, Graphite Furnace Atomic Absorption Spectrometry and X-ray fluorescence spectrometry. X-ray fluorescence allows the simultaneous determination of these elements after ashing of solid recovered fuel (SRF). Direct analysis of the SRF material is not possible by XRF due to the sampl

27、e inhomogeneity and because suitable certified reference materials for calibration are not available. DIN EN 15410:2011-11EN 15410:2011 (E) 5 1 Scope This European Standard specifies three methods of digestion for solid recovered fuels: a) microwave assisted digestion with hydrofluoric, nitric and h

28、ydrochloric acid mixture; b) hot water bath digestion of with hydrofluoric, nitric and hydrochloric acid mixture, after ashing of the SRFs sample; c) oven digestion with nitric, perchloric and hydrofluoric acid mixture. Instrumental determination of Si, Al, K, Na, Ca, Mg, Fe, P, and Ti is performed

29、by Inductively Coupled Plasma Spectrometry with optical detection or other suitable spectroscopic techniques such as Flame Atomic Spectroscopy. The effectiveness of the digestion can be verified by qualitative X-ray fluorescence (XRF) analysis on the remaining residue. If necessary, an alternative d

30、igestion method (among those proposed) shall be used. XRF can be used for the analysis of Si, Al, K, Na, Ca, Mg, Fe, P, Ti, after ashing (550 C) of the sample: other elements can be analysed by XRF provided that the concentration levels are above the instrumental detection limits of the XRF instrume

31、ntation and after proper preliminary testing. Method a) is recommended for general use, but the amount of the test portion can be very low in case of high concentration of organic matter. Method b) is recommended for SRFs with high organic matter concentration that can be difficult to digest with th

32、e other methods. Method c) is recommended for SRFs samples for which the other methods leave a significant insoluble residue. All the listed methods are suitable for the determination of Si, provided that closed containers are used for sample dissolution. XRF is highly recommended for Si, P and Ti a

33、nalysis. Alternative digestion methods can be applied if their performance is proved to be comparable with those of the methods mentioned in a) to c) (see Annex C). 2 Normative references The following referenced documents are indispensable for the application of this European Standard.

39、c matter of a sample and dissolution of its mineral part, more or less completely, when reacted with a reagent mixture 3.2 microwave unit whole microwave digestion system (oven and associated equipment) 4 Safety remarks The safety in handling of potentially hazardous materials is dealt with by the r

40、elevant national and European regulations, which every laboratory should refer to. In addition the following information is given: Only experienced personnel can use the microwave apparatus, following the operating instructions described in the manufacturer manual; Most of the reagents used within t

41、his European Standard are strongly corrosive and toxic. Safety precautions are absolutely necessary due to strong corrosive reagents, high temperature and high pressure; All procedures have to be performed in a hood or in closed force-ventilated equipment. By the use of strong oxidising reagents the

42、 formation of explosive organic intermediates is possible especially when dealing with samples with a high organic content. Do not open pressurised vessels before they have cooled down. Avoid contact with the chemicals and the gaseous reaction products; The X-ray fluorescence spectrometers on the ma

43、rket are generally approved fully protected apparatus. This means that the user is not subjected to any radiation when operating the apparatus. All the apparatus are subject to specific official approval and acceptance conditions; The person responsible for managing or supervising the operation of X

44、-ray equipment shall provide evidence of his knowledge of radiation protection according to national regulations. 5 Principle The test portion is digested using one of the proposed methods with a suitable acid mixture. The digested sample is then analysed by inductively coupled plasma atomic emissio

45、n spectroscopy. DIN EN 15410:2011-11EN 15410:2011 (E) 7 For XRF analysis, the sample is ashed at 550 C and the ash is homogenised in a ball mill to obtain a uniform size dimension of the particles. The ash is then pressed in the form of pellet or fused with tetraborate. Both techniques are suitable

46、for the analysis by XRF. Coal ash and other ashes of various origins can be used for instrument calibration. 6 Apparatus 6.1 Microwave unit Intended for laboratory use and preferably with temperature control. 6.2 Resistance heating oven A resistance heated oven or heating block that can be used at a

47、 temperature of at least 220 C and an accuracy of 10 C. 6.3 Digestion vessels The vessels used in the microwave unit shall be equipped with a pressure relieve valve or another technical equipment which avoids the bursting of the vessels at suddenly occurring excess pressure. The material of the vess

48、els has to be inert to the acids used for digestion. The digestion vessel shall withstand the pressure of at least 8 bar. If the amount of organic carbon exceeds 100 mg it has to be ensured that the digestion vessel is capable of withstanding higher pressures. 6.4 Inductively coupled plasma Normal c

49、ommercial instrumentation with optical or quadrupole mass detector (ICP-OES, ICP-MS). 6.5 X-ray fluorescence spectrometer Energy or wavelength dispersion system suitable for quantitative/qualitative analysis of the elements listed in this European Standard. 6.6 Atomic Absorption Spectrometer Normal commercial instrumentation with air-acetylene burner or with graphite tube atomizer and background correc
