Description

Aluminum Sulfate is an aluminum salt of sulfuric acid, an industrial chemical used in many industrial applications. In purification of drinking water, aluminum sulfate acts as a flocculating agent which causes impurities to coagulate and sediment, so that they are easily removed by filtration. It is also used as a mordant in textile dyeing and paper manufacture.

White crystals

Aluminum sulfate hydrate is a hydrated aluminum salt. Aluminum sulfate is widely used in oil and fat processing, paper manufacturing and as a flocculant for water treatment. The kinetics of its dehydration by thermal decomposition has been investigated. It is one of the components of hematoxylin solution. Spherical particles of aluminum sulfate hydrate has been synthesized by prilling technique.

Drug Information

MeSH：

Substances that augment, stimulate, activate, potentiate, or modulate the immune response at either the cellular or humoral level. The classical agents (Freund's adjuvant, BCG, Corynebacterium parvum, et al.) contain bacterial antigens. Some are endogenous (e.g., histamine, interferon, transfer factor, tuftsin, interleukin-1). Their mode of action is either non-specific, resulting in increased immune responsiveness to a wide variety of antigens, or antigen-specific, i.e., affecting a restricted type of immune response to a narrow group of antigens. The therapeutic efficacy of many biological response modifiers is related to their antigen-specific immunoadjuvanticity. (See all compounds classified as Adjuvants, Immunologic.)

MeSH Entry Terms：

alum

Aluminium sulfate hydrate Use and Manufacturing

Used for water purification, paper making, printing and dyeing, etc.

Al2O3 + 3H2SO4 → Al2(SO4)3 + 3H2O. This reaction treats bauxite with sulfuric acid, resulting in aluminum sulfate plus water. Aluminum sulfate is also known as alum, which acts as an astringent to stop a minor flow of blood or dry up blisters (potassium aluminum sulfate is also an alum).

Aluminum sulfate hydrate is a chemical compound commonly used as a flocculating agent in the purification of drinking water and waste water treatment plants, and also in paper manufacturing. Used as coagulant in decolorization and COD removal of secondary yeast wastewater effluents. It is also plays a significant role in arsenic removal by coagulation process.
