Methods for chemical analysis of tin concentrates
Part 10. Determination of sulfur content
High frequency induction furnace combustion infrared absorption method
And potassium iodate titration
1 Scope
This section GB/T 1819 specifies the determination of sulfur content of tin concentrate.
This section applies to the determination of sulfur in tin concentrate. Method 1 Determination range .0.050% ~ 0.50%; Method 2 Determination of the range.
> 0.50% ~ 20.00%.
2 Method 1 high-frequency induction furnace combustion infrared absorption method
2.1 Method summary
In the presence of flux, into the high-frequency furnace oxygen flow, the sample at high temperature combustion, sulfur dioxide gas into the infrared absorption
The pool, the instrument automatically measures its absorption of infrared energy, and compared with the standard sample, calculate the results.
2.2 Reagents and materials
2.2.1 tin flux. WS ≤ 0.0005%.
2.2.2 pure iron flux. WS ≤ 0.0010%.
2.2.3 Tungsten tin flux. Tungsten tin (93 7), wS ≤ 0.0005%.
2.2.4 tin concentrate standard samples.
2.2.5 steel standard sample.
2.2.6 Carrier gas (oxygen) Purity (volume fraction) not less than 99.95%.
2.2.7 Power gas. Nitrogen or compressed air, the impurities (water and oil) is less than 0.5%.
2.2.8 anhydrous magnesium perchlorate.
2.2.9 caustic asbestos.
2.2.10 rare earth copper oxide.
2.2.11 glass wool.
2.2.12 absorbent cotton.
2.2.13 Platinum-plated silicone.
2.2.14 ceramic crucible (Φ24mm × 24mm), before use should be greater than 1100 ℃ oxygen flow in the burning 1h ~ 1.5h, remove the dry
