Palladium on carbon chemical analysis
Determination of the amount of palladium
Inductively coupled plasma atomic emission spectrometry
1 Scope
This standard specifies the method for the determination of the amount of palladium in palladium on carbon.
This standard applies to the determination of the amount of palladium in palladium on carbon. Measuring range. 0.50% to 10.00%.
2 Method summary
Sample by burning ashed, hydrazine, dissolved hydrochloric acid, nitric acid. Inductively coupled plasma atomic emission spectrometry in selected
Under the conditions, the measured concentration of palladium in the test solution, calculate the amount of palladium.
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 hydrochloride (19).
3.3 nitric acid (ρ = 1.42g/mL).
3.4 80% hydrazine hydrate.
Mixed acid 3.5. 1 volume of nitric acid (3.3), 3 volumes of hydrochloric acid (3.1) mixed, the time is now equipped with.
Palladium 3.6 standard stock solution. Weigh 0.1000g of palladium metal (mass fraction ≥99.99%), placed in 250mL beaker, add 10mL
Mixed acid (3.5), cover the surface of the pan, place on a hot plate over low heat to dissolve. After concentrating to a small volume, was added 20mL of hydrochloric acid (3.1), cooling
To room temperature. Transferred to 100mL volumetric flask, dilute with water to volume, and mix. 1mL solution containing 1mg palladium;
3.7 Yttrium standard solution. Weigh 0.6350g yttria (mass fraction ≥99.95%), placed in 200mL beaker, add 10mL
Hydrochloric acid (3.1), cover the surface of the pan, place on a hot plate over low heat to dissolve. Was added 40mL of hydrochloric acid (3.1), and cooled to room temperature. Moved
500mL volumetric flask, dilute with water to volume, and mix. 1mL solution containing 1mg yttrium.
3.8 argon (volume fraction ≥99.99%).
