1 Scope

YS/T 1115 provisions of this part of the copper ore and tailings Determination of sulfur content. This section applies to the determination of copper ore and tailings sulfur content, high-frequency infrared absorption method for the determination of the range of 0.10% to 18.0%; combustion - iodine Potassium and potassium titration range of 0.10% to 40.0%. 2 methods 1. High-frequency infrared absorption method 2.1 Method summary The sample is heated and combusted in the oxygen flow of the high-frequency induction furnace, the generated sulfur dioxide is loaded into the measurement chamber of the infrared analyzer by oxygen, Sulfur absorption of a specific wavelength of infrared energy, its absorption can be proportional to its concentration, according to the detector to accept the energy change can be measured sulfur mass. 2.2 Reagents Unless otherwise noted, only reagents identified as analytical grade were used in the analysis. 2.2.1 potassium sulfate, reference reagent, content ≥ 99.95%, before use should be dried at 105 ℃ 1h, placed in a desiccator for use. 2.2.2 Silica Content ≥99.95%, powder. 2.2.3 Oxygen, mass fraction ≥99.5%. 2.2.4 caustic asbestos. Particle size 0.7mm ~ 1.2mm. 2.2.5 Anhydrous magnesium perchlorate Particle size 0.7mm ~ 1.2mm. 2.2.6 Iron flux. Sulfur content < 0.0005%. 2.2.7 tungsten particles. Sulfur content < 0.0005%. 2.2.8 tin particles. Sulfur content < 0.0005%. 2.2.9 Ceramic crucible The carbon and sulfur special crucible matched with high frequency induction infrared carbon and sulfur analyzer (2.3.1) should be used before 1200 ℃ Muffle furnace slightly open the door burning 2h, cooled and placed in the dryer spare. 2.2.10 standard sample. The same type of component is similar to the certified standard sample. 2.3 Instruments 2.3.1 high frequency infrared carbon and sulfur analyzer. 2.3.2 analytical balance. Sense of 0.1mg. 2.4 sample Sample size should be not more than 100μm, dried at 100 ℃ ~ 105 ℃ oven for 1h, and placed in a desiccator to cool to room temperature. 2.5 Analysis steps 2.5.1 Sample According to Table 1 weighed sample (2.4), accurate to 0.0001g. ......
