Sample, dilute the slurry H with distilled water to contain Take 3g of the sample with a concentration of 12% of the substance, weigh it to 0.0001, transfer it into 1% milk, add 0.2% sieve copper, 3% sulfuric acid and 2mL of liquid acid, according to the hook, put it in a small bucket. Let it pass through the smoke, and heat it at 45°. First, heat it over low heat until the substance is completely carbonized. Then turn on the ice, increase the heat, and keep the liquid in the bottle slightly boiling. Digest until the substance is dry and transparent. Continue to heat it for 0.5h, cool it down, and carefully add 20ml. After cooling, put it into a 100ml volumetric flask, wash it with water, put it in a small amount, and draw a hundred-marked line. Take the same amount of monosulfate, potassium sulfate, and concentrated sulfur as in the sample treatment as reagents Test. Heat: Set the reagent aside, add water to 23°C in a hot water bottle, add a few drops of red and carbonic acid to make the water acidic, add a few drops of glass fiber to prevent accumulation, heat and boil the water to make the steam. Add 10.0% total acid solution [6.2.5.3d)] 2 drops to a flask, and let the end of the condenser go down, and cool it with water. Pipette 1.0ml of sample digestion solution. Let it flow into the reaction chamber, and use a 10-point small cup to make it enter the reaction chamber, and tighten the small cup. Add hydrogen gas [6.2.5.310ml] into the small cup, and let it condense slowly. Flow into the reaction vessel, plug the glass tightly, and add water to a small glass cup (to prevent it from being full of air). Steam until the water is full, let the money ventilate and let the cold tube enter the flask. Steam for 5 minutes, remove the dust from the cold tube, and then add more! Min. After that, wash the lower end of the cold tube with fire, and stop steaming. Titration: Take out the collection, and titrate with hydrochloric acid standard suspension (D. mol/1) to the end point. Note the external area of the acid standard suspension. The absorption reagent is called the digestion wave. 10mL of the steamed filling is then used as an empty test step. 6.2.5.5 Result calculation
