Determination of imported crude copper smelting or sintered material sulfur content
Frequency combustion infrared absorption method
1 Scope
SN/T 3469 provisions of this part of the high-frequency infrared carbon and sulfur measured imported crude refining of copper or a sintered material determination of sulfur content.
This section applies to imports of copper smelting or sintered material was measured sulfur content. Sulfur measurement range of 0.50% - 25.00%.
2 Method summary
Samples with pure iron and pure tungsten as flux, combustion in an oxygen stream, the sulfur is converted to sulfur dioxide. The use of oxygen stream of sulfur dioxide
The infrared absorption spectrum was measured.
3 Reagents
Unless otherwise indicated, the reagents used were of analytical grade.
3.1 iron flux (C≤0.001%; S≤0.001%).
3.2 flux pure tungsten (C≤0.001%; S≤0.0005%).
3.3 Calcium carbonate. anhydrous calcium sulfate. Before use in 285 ℃ drying 2h, placed in a desiccator to cool.
3.4 magnesium perchlorate (water-absorbing agent).
3.5 alkali asbestos.
3.6 oxygen than 99.5% purity.
3.7 Dynamic gas.
4 instruments and equipment
4.1 high-frequency infrared carbon and sulfur analyzer.
4.2 electronic balance, a sense of the amount of 0.1mg.
4.3 muffle furnace.
4.4 standard sieve.200 mesh.
4.5 porcelain crucible. burning at least 1h before use of air or oxygen at a high temperature (1000 deg.] C), and then stored in a desiccator.
5 Sample Preparation
Specimens shall be passed through a 200 mesh sieve, passed through a 200 mesh sieve to take a sample by quartering shrink into 200g 50g as a sample in
65 ℃ ± 5 ℃ drying 4h, placed in a desiccator, cool to room temperature before use.
Step 6 Analysis
6.1 The instrument parameters
