44、9-07 EN 13753:2009 (E) 9 Annex A (informative) General information on granular activated alumina A.1 Origin A.1.1 Raw materials Granular activated alumina is produced from aluminium hydroxide. A.1.2 Manufacturing process Activated alumina is prepared by the calcination of aluminium hydroxide. Granul
45、ar activated alumina can be prepared by granulation of activated alumina powder or calcination of aluminium hydroxide granules. A.2 Typical properties A.2.1 Chemical composition Activated alumina is a partially calcined aluminium trihydroxide with a combined water content of between a mass fraction
46、of 5 % and a mass fraction of 6 %. The crystal structure is predominantly gamma or chi alumina; small amounts of other forms can be present. The crystal structure can be determined by X-ray diffraction. The chemical composition depends on the origin of the raw material. Typical maximum limits are gi
47、ven in Table A.1, the remainder being Al2O3. Table A.1 Chemical composition of activated alumina Parameter Limit as a mass fraction of the product (typical) in % Water (loss on ignition) 5,5 to 6 Na2O 0,5 Fe2O30,015 SiO20,02 TiO20,002 A.2.2 Physical properties A.2.2.1 Particle size range Examples of
48、 particle size ranges include 1,4 mm to 2,0 mm and 2,0 mm to 4,74 mm. A.2.2.2 Density The absolute density of activated alumina is 3,2 g/cm3; the bulk density can vary with the particle size range. DIN EN 13753:2009-07 EN 13753:2009 (E) 10 A.2.2.3 Adsorption properties Granular activated alumina rem
49、oves contaminants from water by adsorption. A number of indices are used as surrogates for or measures of the adsorptive capacity of granular activated alumina under specific conditions, including specific surface area (BET isotherm). Specifications for such properties can be the subject of agreement between the customer and the manufacturer/supplier and the latter should make the test methods available, if requested.
