Loaded carbon chemical analysis Part 2. Determination of copper and iron Flame Atomic Absorption Spectrometry

1 Scope

This section YS/T 3015 specifies the method for determination of loaded carbon in copper and iron content. This section applies to the determination of gold contained in the carbon content of copper and iron. Measurement range. 0.010% to 2.00% copper; iron ~ 0.010% 1.00%.

2 Method summary

The sample was burning ashed with hydrochloric acid, nitric acid to dissolve the residue. In dilute hydrochloric acid medium, flame atomic absorption spectrometer wavelength 324.8nm and 248.3nm at using air - acetylene flame, copper and iron were measured absorbance, calculated according to the standard curve and copper Iron.

3 Reagents

Unless otherwise indicated in the analysis using only recognized as analytical grade reagents and distilled or deionized water or equivalent purity. 3.1 hydrochloric acid (ρ = 1.19g/mL). 3.2 hydrochloride (11). 3.3 hydrochloride (14). 3.4 nitric acid (ρ = 1.42g/mL). 3.5 copper standard stock solution. Weigh 1.0000g copper (mass fraction ≥99.99%) in 250mL beaker, add 10mL water, Along Beibi added 10mL of nitric acid (3.4), cover the surface of the pan, over low heat until completely dissolved, boil expelled nitrogen oxides, remove the cooled to room temperature. Moved into 1000mL volumetric flask, dilute with water to volume, and mix. 1mL solution containing 1mg of copper. 3.6 Copper Standard Solution. Pipette 25.00mL copper standard stock solution (3.5) in 250mL volumetric flask, was added 25mL of hydrochloric acid (3.3), Dilute with water to volume, and mix. This solution 1mL containing 100μg copper. 3.7 iron standard stock solution. Weigh 1.4297g ferric oxide (excellent pure) in 250mL beaker, add 50mL of hydrochloric acid (3.2), Cover with a watch glass, low heat until completely dissolved, remove the cooling to room temperature. Moved into 1000mL volumetric flask, dilute with water to volume, and mix. 1mL solution containing 1mg iron. 3.8 iron standard solution. Pipette 25.00mL iron standard stock solution (3.7) in 250mL flask, add 25mL of hydrochloric acid (3.3), Dilute with water to volume, and mix. This solution 1mL containing 100μg iron.

4 Instrument
