EN 10184:2006 (E) 4 1 Scope This European Standard specifies a method for the molybdenum blue spectrophotometric determination of phosphorus in non-alloyed steels and
19、irons. The method is applicable to non-alloyed steels and irons with phosphorus contents from 0,005 % to 0,25 % (m/m). 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 r
20、eferences, the latest edition of the referenced document (including any amendments) applies. EN ISO 14284, Steel and iron Sampling and preparation of samples for the determination of chemical composition (ISO 14284:1996) 3 Principle Dissolution of a test portion in nitric and hydrochloric acids and
21、controlled addition of perchloric acid. Formation of the phosphomolybdate complex after removal of silicon and arsenic and reduction with hydrazine sulphate to molybdenum blue. Spectrophotometric measurement of the blue complex at a wavelength of 680 nm or 825 nm. 4 Reagents 4.1 General During the a
22、nalysis, unless otherwise stated, only reagents of recognized analytical grade shall be used and only distilled water or water of equivalent purity. Blank tests shall verify that the relevant reagents are free from phosphorus. Whenever necessary, the results shall be corrected accordingly. Grades gi
23、ving high blank values are unsuitable and should be discarded. 4.2 Hydrochloric acid about 1,19 g/ml. 4.3 Nitric acid about 1,40 g/ml. 4.4 Perchloric acid about 1,67 g/ml. EN 10184:2006 (E) 5 4.5 Hydrofluoric acid about 1,13 g/ml, diluted 1 + 9. 4.6 Hydrobromic acid about 1,47 g/ml, diluted 1 + 1. 4
24、.7 Perchloric acid about 1,67 g/ml, diluted 42 + 58. 420 ml perchloric acid (4.4) shall be carefully poured into 400 ml of water. Swirl, cool, transfer to a 1000 ml volumetric flask. Dilute to the mark with water and mix. 4.8 Sulphuric acid about 1,84 g/ml, diluted 3 + 37. 37,5 ml sulphuric acid ( a
