Description:
Aluminium sulfate is a salt with the formula Al2(SO4)3. It is soluble in water and is mainly used as a coagulating agent (promoting particle collision by neutralizing charge) in the purification of drinking water and wastewater treatment plants, and also in paper manufacturing. The anhydrous form occurs naturally as a rare mineral millosevichite, found for example in volcanic environments and on burning coal-mining waste dumps. Aluminium sulfate is rarely, if ever, encountered as the anhydrous salt. It forms a number of different hydrates, of which the hexadecahydrate Al2(SO4)3·16H2O and octadecahydrate Al2(SO4)3·18H2O are the most common. The heptadecahydrate, whose formula can be written as [Al(H2O)6]2(SO4)3·5H2O, occurs naturally as the mineral alunogen. Aluminium sulfate is sometimes called alum or papermaker's alum in certain industries. However, the name "alum" is more commonly and properly used for any double sulfate salt with the generic formula XAl(SO4)2·12H2O, where X is a monovalent cation such as potassium or ammonium.

Application:
Aluminium sulfate is used
- in water purification and for chemical phosphorus removal from waste water.
- in the human food industry as a firming agent.
- as a mordant in dyeing and printing textiles.
- to reduce the pH of garden soil, as it hydrolyzes to form the aluminium hydroxide precipitate and a dilute sulfuric acid solution
- as waterproofing agent and accelerator in concrete in the construction industry.
- as a foaming agent in fire fighting foam.
Handling and storage
| Handling and storage for Aluminium Sulfate |
| Handling | Avoid dust formation. Keep formation of airborne dusts to a minimum. Provide appropriate exhaust ventilation at places where dust is formed. Do not breathe dust from this material. In case of insufficient ventilation, wear suitable respiratory equipment. Do not get this material in contact with eyes. Avoid contact with skin and eyes. Avoid prolonged exposure. Wash thoroughly after handling. Practice good housekeeping. Emergency eye wash fountains and emergency showers should be available in the immediate vicinity. |
