spectrometry
1 Scope
This Part of YS/T 710 specifies the determination method of calcium, cadmium,
copper, iron, magnesium, manganese, nickel, lead, zinc content in cobalt oxide.
This Part applies to the determination of calcium, cadmium, copper, iron,
magnesium, manganese, nickel, lead, zinc content in cobalt oxide. See Table 1
for the determination range
Table 1 -- Determination range of each element
2 Method summary
Dissolve the sample in aqua regia; in a nitric acid medium, according to the
optimized working conditions of the instrument and the optimized analysis
spectrum, use a standard solution, which is similar to the sample composition,
that matches with the cobalt matrix; use the ICP-AES instrument to determine
the Ca, Cd, Cu, Fe, Mg, Mn, Ni, Pb, Zn content in the cobalt oxide.
3 Reagents
3.1 Hydrochloric acid (ρ1.19 g/mL), GR.
3.2 Nitric acid, (ρ1.42 g/mL), GR.
3.3 Aqua regia: 3 parts of hydrochloric acid (3.1) + 1 part of nitric acid (3.2).
conditions, add 3 mL ~ 5 mL of perchloric acid (3.4) appropriately to smoke until
it is nearly dry.
5.3.2 Blow in a small amount of water; cover the watch glass and boil; cool to
room temperature; add 5 mL of nitric acid (3.2); transfer to a 100 mL volumetric
flask; use water to dilute to the mark; shake well; use as a test solution for later
use.
5.3.3 Measure each point mixed standard solution and test solution under the
optimized working conditions of the instrument; the instrument automatically
draws a working curve.
5.3.4 Test the to-be-tested solution and the blank.
6 Calculation of analysis result
6.1 The instrument, according to the standardization or calibrated
standardization work curve and the set element, automatically processes the
data, calculates and outputs the content of each measured element.
6.2 Keep two significant digits for the analysis result.
7 Precision
7.1 Repeatability
For the measured values of the two independent test results that are obtained
under repetitive conditions, within the average range that is given below, the
absolute difference between the two test results does not exceed the
repeatability limit (r); the case of exceeding the repeatability limit (r) is not more
than 5%; the repeatability limit (r) is obtained by linear interpolation according
to the data in Table 4.
Table 4 -- Repeatability limit
7.2 Reproducibility
For the measured values of the two independent test results that are obtained
under reproductive conditions, within the average range that is given below, the
absolute difference between the two test results does not exceed the
reproducibility limit (R); the case of exceeding the reproducibility limit (R) is not
Note: The repeatability limit (r) is 2.8Sr; Sr is the repeatability standard deviation.
