This section applies to the determination of cadmium in silver content. Measurement range. 0.00020% to 0.0050%.2 principle of the methodSample decomposition with nitric acid, in dilute nitric acid medium, using air - acetylene flame atomic absorption spectrometer measured at a wavelength of 328.1nm Absorbance, using a calibration curve obtained by the amount of silver.3 ReagentsProduction of solutions and experiments with water are double-distilled water. Nitrate 3.1 (ρ1.42g/mL). 3.2 nitric acid (11). 3.3 Cadmium matrix solution. Weigh 20g metal cadmium (wCd≥99.99% and wAg0.0001%), placed in 500mL beaker, fractional total Was added 80mL of nitric acid (3.2), until the vigorous reaction was heated to dissolve completely, purge nitrogen oxides micro-boiling, cooled, transferred to 100mL capacity Dilution bottle with water to volume, and mix. This solution 1mL containing 200mg cadmium. 3.4 Silver standard stock solution. Weigh 0.1000g of metallic silver (wAg≥99.99%), placed in a beaker of 200mL, 10mL of nitric acid was added (3.2), cover sheet pan, heated slowly to dissolve completely removed, washed with water and dish table cup wall, cooled and transferred to 1000mL volumetric flask. 100mL nitric acid (3.2), dilute to the mark and mix. This solution 1mL containing 100μg silver. 3.5 silver standard solution. Pipette 10.00mL silver standard stock solution (3.4) in 1000mL volumetric flask 2mL nitric acid (3.2), Dilute with water to volume, and mix. This solution 1mL containing 10μg silver.4 InstrumentAtomic absorption spectrometer, with a silver hollow-cathode lamp. Under optimum working conditions, who can reach the following indicators are, it can be used. --- Sensitivity. measurement solution matrix consistent solution, features silver concentration should be less than 0.022μg/mL. --- Precision. standard solution with the highest concentration of 10 times the absorbance measurements, the standard deviation should not exceed the average absorbance of 1.0% The lowest concentration of standard solution used (instead of "zero" standard solution) absorbance measured 10 times, and the standard deviation should not exceed the maximum concentration ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of YS/T 74.10-2010_English be delivered?Answer: Upon your order, we will start to translate YS/T 74.10-2010_English as soon as possible, and keep you informed of the progress.
