Aluminum sulfate is a chemical compound known as alum, white alum, aluminum sulfate, papermaking alum. Aluminum sulfate is the most widely used mineral among aluminum compounds. In this article, we are going to talk about aluminum sulfate and also examine the uses, properties and producer of aluminum sulfate 17%.
What is 17% aluminum sulfate?
Aluminum sulfate is a white, solid and crystalline substance that has wide applications. Its chemical formula is Al2(SO4)3. The molar mass of alum is 342.15 g/mol. The most common use of aluminum sulfate is in the paper industry and paper production. Of course, this substance is used in other industries such as water and sewage, textile industries, pH adjustment and resin production. The interesting point is that it is used next to polyaluminum chloride.
Method of production of aluminum sulfate 17%
Aluminum sulfate is widely produced in two ways. Of course, these two methods are the most common methods of producing aluminum sulfate.
Production of aluminum sulfate with sulfuric acid
Aluminum hydroxide is added to sulfuric acid solution. This reaction greatly increases the temperature. In this method, cooling ponds, heat and acid resistant mixers and reactors are used to produce alum.
In the produced aluminum sulfate, the percentage of purity of aluminum is high and its amount is between 85 and 95%.
Production of aluminum sulfate using bauxite soil
The main source of aluminum is bauxite. Carbon bauxite and laterite are the two main types of bauxite. As mentioned, bauxite is used to produce this material, which is one of the most important raw materials. In the following, we will review this method briefly.
Dissolving bauxite: In the first stage of the production of this material, bauxite is dissolved in liquid soda (caustic soda) and sodium aluminate is formed.
Neutralization: In the neutralization stage, sodium aluminate is converted into trialuminum hydrate by adding a neutralizing agent. This composition is collected as sediment in separate tanks.
Adding sulfuric acid: In this step, trialuminum hydrate is added to the solution of sulfuric acid and water.
Heating: the solution is heated until it boils. The process is exothermic and aluminum sulfate is produced by increasing the temperature.

Application and uses of aluminum sulfate
Aluminum sulfate has many uses and we will briefly describe these uses below.
Application of aluminum sulfate in agriculture
Aluminum sulfate is an acidic substance, so it is added to very alkaline soil to control the pH. It is used in planting tomatoes and other vegetables.
Aluminum sulfate controls and changes the pH of the soil, which is why it is used to change the color of some flowers, such as the Dutch flower. A change in the soil of the plant causes the color of the flowers to change. Note that if this substance is not used correctly, it will have an adverse effect on the product or the soil.
Use of aluminum sulfate in dyeing
An important material used in fabric printing and dyeing is aluminum sulfate. By adding a large amount of this substance to water with a neutral pH, aluminum hydroxide is produced. This substance is effective in connecting the color to the fabric fibers. Therefore, this substance is referred to as a color stabilizer. The meaning of the stabilizer is that aluminum hydroxide is combined with fabric and dye molecules and the dye is stabilized on the fabric.
Papermaking and aluminum sulfate industries
Among the uses of aluminum sulfate in the past, it was used in the paper industry, although synthetic materials are used today. In this industry, to change the absorption power of ink, this material is combined with resin soap.
These manufactured papers are not acidic and are used to protect important documents. For this reason, these papers are used in libraries and museums.
Application of aluminum sulfate in water and sewage industry
Aluminum sulfate is used as a coagulant in the water and wastewater treatment industry.
By adding aluminum sulfate to the water, the impurities become lumps and they can be separated through filtration and remove the impurities in the water. Also, this substance removes the turbidity in the water. This property makes it widely used for transparency and increasing the quality of pool water.
It absorbs the hydrogen sulfide gas in the wastewater and destroys it.
Other uses of aluminum sulfate
- Pulp production
- Oil, petrochemical and gas industry
- Textile and dyeing industry
- Purification of water and industrial, agricultural and urban wastewater
- Production of fire extinguisher foam
- Medicine and food industry
- automobile manufacturing
- Production of materials and construction
- Deodorization and degreasing
- Adjustment of soil pH
