alumíniumszulfátot

Alumíniumszulfát, or aluminum sulfate, is a chemical compound with the formula Al₂(SO₄)₃. It is a white, crystalline solid that is soluble in water. It is often encountered in its hydrated forms, such as aluminum sulfate octadecahydrate, Al₂(SO₄)₃·18H₂O.

The primary use of aluminum sulfate is in water purification. It acts as a flocculant, causing suspended particles in water to clump together, making them easier to remove through filtration. This process is essential for producing clean drinking water and treating wastewater.

Another significant application is in the paper industry, where it is used as a sizing agent. It helps to improve the strength and water resistance of paper by reacting with cellulose fibers. In dyeing processes, aluminum sulfate acts as a mordant, helping dyes adhere better to fabrics.

Aluminum sulfate also finds use in construction, particularly in the production of concrete and cement, where it can accelerate hardening. It is also employed in some agricultural applications as a soil additive to lower pH, although its use in this regard requires careful management. In medicine, it has historically been used as an astringent.

The production of aluminum sulfate typically involves reacting aluminum hydroxide or bauxite ore with sulfuric acid. It is a widely produced and economically important chemical with diverse industrial applications.
