46、nformation on iron-coated granular activated alumina A.1 Origin A.1.1 Raw materials Granular activated alumina is produced from aluminium hydroxide. Following manufacture of the high surface area granular activated alumina, conforming to EN 13753 (see 3), is coated with iron using iron(III) sulfate

47、conforming to EN 890 (see 4). A.1.2 Manufacturing process Activated alumina is prepared by the calcination of aluminium hydroxide. Granular activated alumina can be prepared by granulation of activated alumina powder or calcination of aluminium hydroxide granules. Iron-coated activated alumina is pr

48、epared by coating of granules of activated alumina with insoluble iron using a solution of iron(III) sulfate. A.2 Typical properties A.2.1 Chemical composition Activated alumina is a partially calcined aluminium trihydroxide with a combined water content of mass fraction between 5 % and 6 %. The cry

49、stal 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 limits are given in Table A.1, the remainder being Al2O3.
