EN 15916-2:2010 (E) 4 1 Scope This European Standard specifies a flame atomic absorption spectrometric method (FAAS) for the determination of the tellurium content of copper and copper alloys in form of castings or unwrought or wrought products. The method is applicable to products having tellurium mass fractions between 0,20 % and 1,00 %. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO 1811-1, Copper and copper alloys — Selection and preparation of samples for chemical analysis — Part 1: Sampling of cast unwrought products ISO 1811-2, Copper and copper alloys — Selection and preparation of samples for chemical analysis — Part 2: Sampling of wrought products and castings 3 Principle Dissolution of a test portion in nitric acid followed, after suitable dilution, by aspiration into an air/acetylene flame of an atomic absorption spectrometer. Measurement of the absorption of the 214,3 nm line emitted by a tellurium hollow-cathode lamp. 4 Reagents During the analysis, use only reagents of recognized analytical grade and only distilled water or water of equivalent purity. 4.1 Nitric acid, HNO3 (ρ
= 1,40 g/ml). 4.2 Hydrochloric acid, HCl (ρ
= 1,19 g/ml). 4.3 Nitric acid solution, 2 + 1. Add 200 ml of nitric acid (4.1) to 100 ml of water. 4.4 Hydrochloric acid solution, HCl (2 mol/l). In a 1 000 ml one-mark volumetric flask containing about 500 ml of water, add 165 ml of hydrochloric acid (4.2). Dilute to the mark with water and mix well. 4.5 Tellurium stock solution, 1 g/l Te. Weigh (0,5 ± 0,001) g of tellurium (Te > 99,9 %) and transfer it into a 250 ml beaker. Add 10 ml of nitric acid solution (4.3) and dissolve on a water bath. Evaporate to a wet residue, and then dissolve in 10 ml of hydrochloric acid solution (4.4). Transfer to a 500 ml one-mark volumetric flask, dilute to the mark with hydrochloric acid solution (4.4) and mix well. 1 ml of this solution contains 1,0 mg of Te. SIS
