It is soluble in water and dissolves in various organic solvents (methanol, ethanol). NOTE The reaction with organics can be violen
37、t and is not recommended. It decomposes at a high temperature and also in the presence of concentrated acids, hydrogen peroxide and organic compounds in general. It hydrolyses very slowly in contact with air, reducing to manganese dioxide (MnO2), a solid, brown to black colour product. 4 Purity crit
38、eria 4.1 General This European Standard specifies the minimum purity requirements for sodium permanganate used for the treatment of water intended for human consumption. Limits are given for impurities commonly present in the product. Depending on the raw material and the manufacturing process other
39、 impurities may be present and, if so, the user and when necessary to relevant authorities shall be notified. NOTE Users of this product should check the national regulations to clarify whether it is of appropriate purity for treatment of water intended for human consumption, taking into account raw
40、 water quality, required dosage, contents of other impurities and additives used in the product not stated in this product standard. Limits have been given for impurities and chemical parameters where these are likely to be present in significant quantities from the current production process and ra
41、w materials. If the production process or raw materials leads to significant quantities of impurities, by-products or additives being present, the user shall be notified. 4.2 Composition of commercial product The sodium permanganate is usually available in a concentrated solution with a concentratio
42、n within the range of mass fraction of 20 % to 40 %. The concentration of sodium permanganate solution shall be equal to or greater than the manufacturer specified value. 4.3 Impurities and main by-products The content of manganese dioxide (insoluble matter) shall be no more than a mass fraction of
43、0,055 %. NOTE The product can contain fluoride or hexafluorosilicate. At typical levels of dosing, the added fluoride would be less than 40 g/l.

46、ampled by shaking the container, by rolling it or by rocking it from side to side, taking care not to damage the container or spill any of the liquid. 5.1.2.1.2 If the design of the container is such (for example, a narrow-necked bottle) that it is impracticable to use a sampling implement, take a s
47、ample by pouring after the contents have been thoroughly mixed. Otherwise, proceed as described in 5.1.2.1.3. 5.1.2.1.3 Examine the surface of the liquid. If there are signs of surface contamination, take samples from the surface as described in 5.1.2.2. Otherwise, take samples as described in 5.1.2
48、.3. 5.1.2.2 Surface sampling Take a sample using a suitable ladle. Lower the ladle into the liquid until the rim is just below the surface, so that the surface layer runs into it. Withdraw the ladle just before it fills completely and allow any liquid adhering to the ladle to drain off. If necessary
49、, repeat this operation so that, when the other selected containers have been sampled in a similar manner, the total volume of sample required for subsequent analysis is obtained.
