| titleOfInvention | Method of producing magnetite with developed surface |
| abstract | FIELD: chemistry. n SUBSTANCE: invention can be used in chemical industry. The method of producing magnetite with a developed surface involves preparation of iron (II) chloride and iron (III) nitrate solutions and draining the solutions of the obtained salts. Carbonyl iron is used to obtain the iron salts. Iron (III) nitrate is obtained by adding 50-60 ml of 3% hydrogen peroxide solution. A protective toluene film forms over the iron (II) chloride solution. The mixture of iron (II) chloride and iron (III) nitrate solutions is then precipitated with a solution which is prepared by pouring 1 litre of 25% ammonia solution to 8 litres of distilled water while stirring intensely. n EFFECT: invention increases specific surface area of magnetite to 130 m 2 /g. n 1 ex |
