Appendix A
(Normative)
Determination of boron content in lithium carbonate -- Inductively coupled
plasma atomic emission spectrometry
A.1 Overview
This Appendix is applicable to the determination of boron content in lithium carbonate,
which has a determination limit of 0.000050% ~ 0.010% boron content.
A.2 Principle
The sample is dissolved in hydrochloric acid. The boron content is determined by the
standard working curve method on an inductively coupled plasma atomic emission
spectrometer.
A.3 Reagents or materials
Unless otherwise specified, only reagents confirmed to be of superior purity are used in
the analysis. Boron-containing vessels shall be avoided during the experiment.
A.3.1 Water, GB/T 6682, grade 2.
A.3.2 Hydrochloric acid (ρ = 1.19 g/mL).
A.3.3 Hydrochloric acid (1 + 1).
A.6.1 Test material
Weigh the test material according to Table A.1, accurate to 0.0001 g.
A.6.2 Parallel test
Perform two tests in parallel.
A.6.3 Blank test
Perform a blank test with the test material.
A.6.4 Determination
Place the sample (A.6.1) in a 200 mL polytetrafluoroethylene beaker. Add a small
amount of water to moisten it. Slowly add 23 mL of hydrochloric acid (A.3.3).
A.6.5 Preparation of working curve solution
A.6.6 Determination
A.6.6.1 Place the standard working curve series solution (A.6.5) in an inductively
coupled plasma atomic emission spectrometer, to measure it according to the analytical
spectrum recommended by the equipment. Draw the working curve with the mass
concentration of the boron element standard solution as the abscissa and the emission
intensity as the ordinate.
A.6.6.2 When the linearity of the working curve is ≥ 0.999, measure the blank test
solution and the test solution; the computer automatically gives the mass concentration
of the boron element.
A.7 Test data processing
The content of boron is calculated by mass fraction according to formula (A.1).
