DIN EN 15411:2011-11 EN 15411:2011 (E) 4 Introduction Accurate determination of trace element content in solid recovered fuels is important for environmental and technical reasons

    23、 both in the production and combustion stage. 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, graphite furn

    24、ace Atomic Absorption Spectrometry and, when available, dedicated specific method (e.g. for mercury). DIN EN 15411:2011-11 EN 15411:2011 (E) 5 1 Scope This European Standard specifies three methods of digestion for solid recovered fuels: a) microwave assisted digestion with hydrofluoric, nitric and

    25、hydrochloric 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 As, Ba, Be, Cd, Cr, Co, Cu, Pb, Mn, Mo, Ni, Sb, S

    26、e, Tl, V, Zn is performed by Inductively Coupled Plasma with optical or mass detection or graphite furnace Atomic Absorption Spectrometry. Hg can be analysed only after the microwave assisted procedure or, alternatively, by a direct analysis method (Hg direct AMA). The effectiveness of the digestion

    27、 can be verified by qualitative X-ray fluorescence (XRF) analysis on the remaining residue. If necessary, an alternative digestion method (among those proposed) is used. Method a) is recommended for general use, but the amount of the test portion can be very low in case of high concentration of orga

    28、nic matter. Method b) is recommended for Solid Recovered Fuel (SRF) with high organic matter concentration that can be difficult to digest with the other methods. This method is not suitable for mercury. Method c) is recommended for Solid Recovered Fuel (SRF) samples for which the other methods leav

    29、e a significant insoluble residue. 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 Europ

    30、ean Standard. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

    34、crowave digestion system (oven and associated equipment) 4 Safety remarks The safety in handling of potentially hazardous materials is dealt with by the relevant national and European regulations, which every laboratory should refer to. In addition the following information is given: Only experience

    35、d personnel can use the microwave apparatus, following the operating instructions described in the manufacturer manual; Most of the reagents used within this European Standard are strongly corrosive and toxic. Safety precautions are absolutely necessary due to strong corrosive reagents, high tempera

    36、ture 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 formation of explosive organic intermediates is possible, especially when dealing with samples with a high organic content. Do not open pressuris

    37、ed vessels before they have cooled down. Avoid contact with the chemicals and the gaseous reaction products. 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 the most appropriate spectrometric technique,

    38、such as atomic absorption or emission spectroscopy. 6 Apparatus 6.1 Microwave unit Intended for laboratory use and preferably equipped with temperature control. 6.2 Resistance heating oven A resistance heated oven or heating block that can be used at a temperature of at least 220 C and an accuracy o

    39、f 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 vessels has to be inert to the acids used for digest

    40、ion. 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 DIN EN 15411:2011-11 EN 15411:2011 (E) 7 Normal commerc

    41、ial instrumentation with optical or mass spectrometric detector (ICP-OES, ICP-MS). 6.5 Atomic absorption spectrophotometer Normal commercial instrumentation, equipped with graphite furnace or hydride generation systems or cold vapour (GF-AAS, HG-AAS, CV-AAS). 6.6 X-ray fluorescence spectrometer Ener

    42、gy or wavelength dispersion system suitable for qualitative analysis of the elements listed in this European Standard (with the exception of beryllium). 6.7 Balances Analytical balance resolution 0,1 mg. 6.8 General equipment General laboratory equipment, including volumetric graduated flasks and pi

    43、pettes of adequate size. Filter equipment of adequate chemical resistance and purity or centrifuge. The use of glassware shall be excluded when free hydrofluoric acid is present. The glassware used in the digestion procedure should be carefully pre-cleaned with for example 10 % nitric acid solution.

    44、 7 Reagents All reagents shall be at least of analytical grade and suitable for their specific purposes. Other specific reagents are listed and described in the reference methods for digestion or instrumental determination listed in Clause 2. NOTE Acids used in the preparation of standards and for s

    45、ample processing are of high purity. Redistilled acids are recommended because of the high sensitivity of ICP-MS. Nitric acid at less than 2 % (v/v) is recommended for ICP-MS to minimize damage to the interface and to minimize isobaric molecular-ion interferences with the analytes. Many more molecul

    46、ar-ion interferences are observed when hydrochloric and sulphuric acids are used. 7.1 Water of grade 1 as specified by EN ISO 3696:1995. 7.2 Nitric acid (HNO3), 65 % (w/w), 1,40 g/ml. 7.3 Hydrofluoric acid (HF), 40 % (w/w), 1,14 g/ml. 7.4 Perchloric acid (HClO4), 70 % (w/w), 1,62 g/ml. 7.5 Hydrochlo

    47、ric acid (HCl), 65 % (w/w), 1,40 g/ml. 8 Procedure 8.1 Sample conservation and pre-treatment The laboratory samples shall be stored according to guidelines defined in Annex A. DIN EN 15411:2011-11 EN 15411:2011 (E) 8 It is advisable to contact the people performing the sampling in order to agree a p

    48、rocedure for the laboratory sample preparation and storage before delivering to the laboratory. In particular, any treatment procedure which can increase the temperature of the material above 40 C should be avoided, in order to avoid significant loss of mercury or other volatile compounds. Furthermo

    49、re, any possible source of contamination during the laboratory sample preparation (e.g. grinding with metallic apparatus) shall be avoided or reduced as much as possible. The laboratory sample should be stored and delivered in sealed high-density plastic containers. 8.2 Sample preparation The test portion shall be prepared from the laboratory sample according to EN 15413. In addition, for the purposes of this method, t
