The historical version replaced by this Part is as follows.
- GB/T 11064.9-1989.
Methods for chemical analysis of lithium carbonate,
lithium hydroxide monohydrate and lithium chloride -
Part 9. Determination of sulfate content –
Barium sulfate nephelometry method
1 Scope
This Part of GB/T 11064 specifies the determination method of sulfate content in lithium
carbonate, in lithium hydroxide monohydrate, and in lithium chloride.
This Part applies to the determination of sulfate content in lithium carbonate, in lithium
hydroxide monohydrate, and in lithium chloride. The determination range. 0.0050% ~
0.80%.
2 Method Summary
In hydrochloric acid medium, the barium ions and sulfate ions will generate the insoluble
barium sulfate. Within a certain time, the barium sulfate is suspended in the solution;
measure its absorbance at 420nm wavelength of spectrophotometer to obtain the content
of sulfate.
3 Reagents
Unless otherwise specified, the reagent used in this Part is an analytical pure reagent, and
the water used in this Part is the secondary deionized water.
3.1 Hydrochloric acid (1+1), GR.
3.2 Hydrochloric acid (1+3), GR.
3.3 Ammonium Hydroxide (1+3), GR.
3.4 Glycerol solution (1+4).
3.5 Barium chloride solution (200 g/L). prepare when it is used.
3.6 Paranitrophenol indicator (1 g/L).
3.7 Sulfate standard stock solution. weigh 0.907 5 g of potassium sulfate (GR) which has
been baked for 2h at the temperature of 105°C~110°C in advance, and placed in dryer to
cool to room temperature. Place it in a 250mL beaker; dissolve with water; transfer to a
