1 Scope

This standard specifies the lead, copper, iron determination of the amount of palladium on charcoal. This standard applies to lead, copper, iron in determining the amount of palladium on carbon. Measurement range. 0.010% to 0.10%.

2 Method summary

Sample with nitric acid, perchloric acid digestion, activated charcoal until digestion was complete, the selected emission spectrometer inductively coupled plasma atomic article in Under parts, measuring the mass concentration of each element in the test solution, the calculation of lead, copper and iron.

3 Reagents and materials

Unless otherwise indicated, in the analysis using only the confirmation of analytical grade reagents and distilled water again. 3.1 hydrochloric acid (ρ = 1.19g/mL). 3.2 nitric acid (ρ = 1.42g/mL). 3.3 perchloric acid (ρ = 1.42g/mL). 3.4 nitric acid (19). 3.5 lead standard stock solution. Weigh 0.1000g metallic lead (Pb mass fraction ≥99.99%), placed in 100mL beaker, add 10mL water, 10mL of nitric acid (3.2), cover the surface of the pan, over low heat to dissolve. Cooling to room temperature, transferred to 100mL volumetric flask, dilute with water Explanation to the mark. Mix well. 1mL solution containing 1mg lead. 3.6 copper standard stock solution. Weigh 0.1000g copper (mass fraction of copper ≥99.99%), placed in 100mL beaker, add 10mL water, 10mL of nitric acid (3.2), cover the surface of the pan, over low heat to dissolve. Cooling to room temperature, transferred to 100mL volumetric flask, dilute with water Explanation to the mark. Mix well. 1mL solution containing 1mg of copper. 3.7 iron standard stock solution. Weigh 0.1430g ferric oxide (Fe2O3 mass fraction ≥99.99%), placed in 100mL beaker Added 10mL of water, 10mL of hydrochloric acid (3.1), cover the surface of the pan, over low heat to dissolve. Cooled to room temperature, transferred to 100mL volumetric flask Diluted with water to the mark. Mix well. 1mL solution containing 1mg iron. 3.8 Lead copper and iron mixed standard solution. Pipette 10.00mL were lead, copper, iron standard stock solution (3.5, 3.6) in 100mL flask The use of nitric acid (3.4) diluted to the mark, and mix. This solution 1mL lead containing 100μg, 100μg copper, 100μg iron. 3.9 argon (volume fraction ≥99.99%).
