1 Scope

YS/T of the provisions of section 710 of the method for the determination of the amount of sodium cobalt oxide. This section applies to the determination of the amount of sodium cobalt oxide. Measurement range. 0.0010% to 0.020%.

2 Method summary

Sample decomposition with hydrochloric acid, hydrochloric acid medium, cesium chloride as an inhibitor, atomic absorption spectrometer at a wavelength of 589nm, the use of air - Acetylene flame measured absorbance sodium. Calculate the amount of sodium by the working curve method.

3 Reagents

3.1 commercially available reagents Hydrochloric acid (ρ1.19g/mL), pure class distinctions. 3.2 solution Cesium chloride solution (5g/L). formulated with spectroscopically pure cesium chloride. 3.3 standard solution 3.3.1 Sodium standard stock solution. Weigh 0.2542g sodium chloride (excellent pure) (pre-dried in an oven at 110 ℃ 2h and dried Vessel was cooled to room temperature), placed in a quartz 150mL beaker, deionized water and dissolved moved 1L volumetric flask, dilute with deionized water to Mark, moved into a plastic bottle. This standard stock solution containing sodium 1mL 0.1mg. 3.3.2 Sodium standard solution. Pipette 5.00mL sodium standard stock solution (3.3.1) into 100mL flask, diluted with deionized water to Mark, shake and then transferred to a plastic bottle for storage. This solution 1mL containing 5μg sodium.

4 Instrument

Atomic absorption spectrometer, with a sodium hollow cathode lamp. Under optimum working conditions for those who can reach the following indicators can be used. --- Characteristic concentration. in the measurement sample solution matrix consistent solution, characterized in sodium concentration should not exceed 0.25μg/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 0.5% of the mean absorbance of standard solution. Linear curve. The curve is divided into five sections according to concentration, than the difference between the absorbance of the absorbance difference between the highest and the lowest segment segment, It should not be less than 0.7. AAS Reference operating conditions. --- Wavelength of 589nm; --- Lamp current 2.0mA; --- Stoichiometric flame atomic zone determination. ......
