Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces SN/T 2263-2009 "Inductively Coupled Plasma Mass Spectrometry for the Determination of Arsenic, Bromine and Iodine in Coal or Coke". versus
Compared with SN/T 2263-2009, the main technical changes except editorial changes are as follows.
--- Redefined the measurement range of bromine and iodine in the standard;
--- Modified "4 reagents and materials" and added "4.4 ammonia";
--- Modified "4 reagents and materials", the cleaning solution was modified to "take 5mL ammonia (4.4), placed in a 500mL plastic volumetric flask, add water
Mix"
--- Modified "5 instruments" and added "5.4 plastic volumetric flasks, 100mL";
--- Revised "7.4 standard solution working curve drawing", the standard solution concentration was modified to "standard 1.15, 30, 15, 10; standard 2.30, 60,
30, 10; standard 3. 100,.200, 100, 10".
This standard is proposed and managed by the National Certification and Accreditation Administration.

3 method summary
The sample is pre-digested by nitric acid, then subjected to high temperature pressure microwave sealing digestion---mixed acid solution treatment, and then stabilized by the oxidant, diluted
After constant volume determination, indium was used as an internal standard for ICP-MS determination. The quantitative relationship between mass-to-charge ratio intensity and its elemental concentration was used to determine arsenic, bromine and iodine in the sample.

4 reagents and materials
Unless otherwise stated, this standard uses only analytically pure and above reagents, water is double distilled water or water of comparable purity. If there is a
A sub-boiling distilled water can be used.
4.1 Nitric acid (excellent grade, ρ = 1.42g/mL).
4.2 Hydrofluoric acid (analytically pure, HF ≥ 40%).
4.3 Hydrogen peroxide (analytically pure, H2O2 ≥ 30%).
4.4 Ammonia.
4.5 Boric acid.
4.6 Nitric acid (1 1).
4.7 Nitric acid (1/9).
4.8 Tetrafluoroboric acid, 50% (mass fraction).
