Aluminum sulfate, as an indispensable inorganic chemical raw material, has a wide range of applications across multiple industrial fields. Below, I will explain the characteristics of this chemical product and its important role in water treatment from multiple perspectives such as molecular structure, key parameters, and application functions.
The molecular formula of aluminium sulfate is KAl(SO4)2·12H2O, where K, Al, SO4 and H2O represent potassium, aluminum, sulfate and crystal water, respectively. It presents a white crystalline form, has no odor, no irritating taste, and can quickly dissolve in water to form an acidic solution.
The following are some key indicators to measure the quality of Aluminium Sulphate:
- Appearance: It should be a white crystalline solid.
- Purity: not less than 98%.
- Water-insoluble content: not more than 0.5%.
- Chloride content: not more than 0.05%.
- Sulfate content: not more than 0.5%.
- Heavy metal content (in terms of lead): not more than 0.001%.
Aluminum sulfate is widely used in the following fields:
- As a water treatment agent, it has excellent flocculation, precipitation and adsorption capabilities, effectively improving water quality.
- In the leather industry, aluminum sulfate is used as a tanning agent to enhance the flexibility and durability of leather.
- In the printing and dyeing industry, it is used as a mordant to enhance the binding force between dyes and fibers and improve the dyeing effect.
- Aluminum sulfate can also be used in the preparation of pesticides, such as Bordeaux mixture.
- In the papermaking industry, it is used as a sizing agent to improve the water resistance and strength of paper.
- In the ceramic industry, aluminum sulfate is used as a flux to reduce the firing temperature and improve product quality.
- In addition, it also plays an important role in the food, medicine, cosmetics and other industries, such as food additives and pharmaceutical raw materials.
In-depth analysis of the application value of aluminum sulfate in various fields
Through the above introduction, it is not difficult to see that aluminum sulfate is widely used and has an irreplaceable role in many industrial fields. Next, I will further explore its specific application value in different fields and the benefits it brings.

Analysis of the application of aluminum sulfate in water purification
1. Flocculation function: Aluminum sulfate dissolved in water releases a large amount of Al3+ ions, which neutralize the charge of suspended particles and colloidal substances in the water body, causing them to aggregate into larger flocs for easy sedimentation.
2. Reduction of hardness: Reacting with calcium and magnesium ions in water, aluminum sulfate can form insoluble calcium sulfate, magnesium sulfate and other precipitates, effectively reducing the hardness of the water body.
3. Adsorption efficiency: With its high specific surface area, aluminum sulfate can adsorb organic pollutants and microorganisms in water, thereby optimizing water quality.
4. Color removal: Aluminum sulfate has a good removal effect on pigments and odor substances in water, significantly improving the transparency of water bodies.
5. Anti-corrosion effect: Aluminum sulfate has a certain anti-corrosion ability, which can inhibit the growth of microorganisms in water and extend the shelf life of water resources.
In summary, as an efficient and environmentally friendly water treatment agent, the application prospects of aluminum sulfate have attracted much attention in the water treatment industry. With the advancement of science and technology and the enhancement of environmental awareness, the value of aluminum sulfate in water treatment will be further highlighted.
