This standard specifies two methods for the analysis of the content of monovalent alcohol in sucrose ore: the loss of alcohol method and the short supply method. This standard applies to the determination of the content of sucrose ore in the range of 13.%~2. Method 1 (long-term solution)
2.1 Method 1 (long-term solution)
The material is separated by hydrochloric acid, nitric acid and chlorinated acid. In dilute sulfuric acid or acid, the two copper sulfides are dissolved in the form of copper sulfide: it is separated from the surface of the lower element. The standard acid is adjusted to a value of -0. The standard is used as a reference for the determination of the content of sulphur by the reaction of potassium with divalent potassium. The sodium plate was filled to a certain volume and the sample was measured by the original copper absorption method (2.2 short volume). The sample was cut with salt and the acid was released. The solution was added with acetic acid (1.3). The value of the solution was 3. (1.3. Use cumulative acid or the acid drink to cover it. Add iodine and use a needle. Use the amount of the reagent as an indicator. Add 3 drops of sodium thioaldehyde standard solution. 3.1 drops of potassium iodide, 3.2 drops of magnesium sulfate (3.16) μm, and place the tablets in ice water.

Put the sample (5.1) in a 5r: push-shaped beaker with a little water: add 1(m) acid and heat it on the electric heating plate at low temperature for 1~5, remove it from the oven, add 1ral. age who (3.1) and f.5m. excitation, add a spoon, heat at low temperature, and wait until the material is completely decomposed. , then heat and steam, and cool. 6.3.1-2 bottles of island
with 90mL of this selected blood and cup rate, 10mL of system chain (3.13 before 3-electric heating or on, slowly add 23:L anti-surrogate calcium squeeze micro (.2), need to take 5min, keep warm until the precipitate is affinity, melt hot filter, state currency refreshing water wash anti-diameter structure three times on: flow filtration and separation high-efficiency decomposition and concentration combined with atomic multi-light false increase sales. 6.3.1.3 Anti-resistance difference grouping
etc. precipitate and paper return flow cup add human acid (315). Thermal decomposition precipitate and paper (with carbon flow, can be appropriate, heat until complete decomposition), and cool to 6. 3.7.4 titration
Use water and oil to wash the whole cup, cover the table, place on the electric hot plate to make the three drops of the solution, cool to room temperature, add hydrogen water until the material is 20%, then add glacial acetic acid (3.1E) to precipitate the structure, the excess. Add ultraviolet and braid liquid, violent. The child is 2-1 only lacks the standard chemical operation, immediately use the standard sodium limit (3.25) titration rate to get a light blue color. Cut into 2I gel, continue to adjust until there is no tooth color, add 5 more lithium drop solution than the original, the effect is strong and the base blue is deep, the sequence is set as the end point when the base blue fish just disappears.
6.3.1.5 Determination of full concentration
Put the sample in a water-heated cabinet and boil it for 2 hours. Remove the sample and cool it down. Add water to a volumetric volume and dilute it to the mark. Mix well and keep it for 2 hours. Heat the sample in the same air as in the previous step. Use an atomic absorption spectrometer at a wavelength of 32.7° and a lamp as the background. At the same time as the actual test, measure the absorbance of the sample before and after the concentration drops to the test cell. The corresponding curve will be plotted on the graph.)
6 3.1.6 Preparation of filter line, GH/T 3884. 1—2000 6.3.1.6.1 Transfer 1, 1.6, 2.00, 3.09, 1.00, 5.1 mL of standard samples into a set of 200L storage bottles, add 1.0 mL of common acid (.1.8), and dilute with water to the standard. 6.3.1.6.7 Use a gas-fired fast flame to record the atomic absorption light at the wavelength of 24.7 nm, and adjust to zero with water. Use the light source to obtain the absorbance of the light box at "zero", use the absorption of steel as the coordinate and the frequency coordinate, and make a curve. 6.3.2 Method 2 (Determination by short-term method) 6.3.2. 1 Preparation of sample Place the sample (1) in a 5 μm 1.5-dimensional beaker, moisten it with a little water, add 11 ml of acetic acid, place it on a hot plate and moisten it for 3-5 min, remove it and cool it, add 5 ml of triturated acid (3%) and mT. Au, cover it with a watch and heat it at a low temperature. When the sample is completely decomposed, remove it and cool it slightly, wash the watch with a little water, continue heating to nearly ten degrees, and cool it. Note: When the silicon content in the sample is significantly higher, add 1.5 g of oxidative stress (I3-5). 2. When the content of the material is close to the commercial value, make 2 ~ m high oxygen, heat and no black flow, evaporate to dryness, chemical (3.5 high || tt || 6-3-2.2 fixed || tt || rinse the blood battle cup with 311ml. water, cover the table, put it on the hot plate to boil, so that the viable salts are completely dissolved, remove and cool to room temperature, add 7. until the red is no longer deep and pass through the plate 3--=mL, heat and add ammonium oxide <5.17> until the red is eliminated. Add 1mL of excess, continent. Add 2-3R According to the results of the experiment, the standard for smallpox infection is the concentration of starch (3.251, determined to be light yellow: and the concentration of L starch, continue to titrate until the color is light yellow, which is the burning point. If the content is relatively low, 1mL of three-phase solution is required. 2 phase, fast salt reduction requires 2m in advance:. The starch solution shows the decay of the analysis results. 7.1 Method 1 (long-term quantitative method) Calculate the content of the starch solution using formula (2): 7.2 Method 21 Standard quantitative method17. :x ~27.
