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%).

4 Instrument

Inductively coupled plasma atomic emission spectrometer (operating parameters, see Appendix A). Under optimum working conditions for those who can reach the following indicators can be used. --- Source. argon plasma light source, the generator maximum power output of not less than 1.30kW. --- Resolution. The 200nm optical resolution of not more than 0.010nm; at 400nm optical resolution no greater than 0.020nm. --- Instrument stability. 1h instrument drift within not more than 2.0%.

5 Sample

Uniform sample preparation, particle size should be less than 0.074mm.
