Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
Instead of the standard SN/T 0561-1996 "export natural flake graphite in acid-soluble iron content by atomic absorption spectrometry method."
In addition to this standard editorial changes, the increase of the "washed free of iron ions until the" judging method (see 6.3.1 and 6.3.1 of the 1996 edition).
This standard is proposed and managed by the National Certification and Accreditation Administration Committee.
This standard was drafted. People's Republic of China Hebei Exit Inspection and Quarantine.
The main drafters of this standard. Lin Yang, Yuan Wang V, Gu Yansheng.
This standard replaces the standards previously issued as follows.

3 Method summary
In a sample with hydrochloric acid soluble iron dissolved in hydrochloric acid medium, at an atomic absorption spectrophotometer at a wavelength of 248.3nm, air - B
Alkyne flame determination of iron absorbance.
4 Reagents
Unless otherwise indicated, the reagents used were of analytical grade water to comply with two water GB/T 6682-2008 requirements.
4.1 hydrochloric acid (ρ = 1.19g/mL).
4.2 nitric acid (ρ = 1.42g/mL).
4.3 KSCN.
4.4 potassium permanganate.
4.5 iron standard stock solution. Weigh 1.0000g high iron (99.99%) in the beaker, add 50mL water, 50mL of nitric acid (4.2), cover
Watch glass, heat until completely dissolved; then, add water, 20mL, boiled, to expel oxides of nitrogen, cooled and transferred to 1000mL volumetric flask
Dilute with water to volume, and mix. 1mL solution containing 1mg iron. You can also use a commercially available certified reference solution.
4.6 iron standard solution. Pipette 10.00mL iron standard stock solution (4.5) in a volumetric flask, dilute with water to volume, and mix. This solution
1mL containing 100μg iron.
4.7 hydrochloride (11).
4.8 hydrochloric acid (199).
4.9 thiocyanate solution (1%). take 1g thiocyanate (4.3) were dissolved in 100mL water.
4.10 acidic potassium permanganate solution (1%). Weigh 1g potassium permanganate (4.4), was dissolved in 100mL dilute sulfuric acid (14) in.
5 Instruments
Atomic absorption spectrophotometer, with iron hollow cathode lamp.
