Difference between iron-free aluminum sulfate and aluminum sulfate

The main difference between ironless aluminum sulfate and aluminum sulfate lies in their chemical composition, physical properties and uses. The following is a detailed introduction:

The main difference between ironless aluminum sulfate and aluminum sulfate lies in their chemical composition, physical properties and uses. The following is a detailed introduction:
1.Chemical composition. The chemical formula of aluminum sulfate is Al2(SO4)3, which is made by the reaction between sulfuric acid and aluminum hydroxide; the chemical formula of iron-free aluminum sulfate is Al2(SO4)3-xH2O, in which x is usually less than 3, which is made by the reaction between aluminum hydroxide and sulfuric acid, and it does not contain or contains little iron.
2. Physical Properties. Aluminum sulfate usually appears as odorless, white, hygroscopic, glossy crystals or powder, and its density is 1.69 g/mL (25°C); iron-free aluminum sulfate usually appears as white granules or lumps, and its density is 2.71 g/mL.
 

Aluminum sulfate is mainly used in papermaking and water purification industry, it can be used as mordant, tanning agent, pharmaceutical astringent, wood preservative, foam fire extinguishing agent, etc.; iron-free aluminum sulfate is used in papermaking, special water treatment, titanium dioxide production and filler, etc. Iron-free aluminum sulfate can be used as a paper sizing agent in the papermaking industry, to enhance the water-resistant and seepage-proof performance of the paper, and can also be used as a water supply and wastewater coagulant, turbid water purifying agent, precipitating agent, It can also be used as water supply and wastewater coagulant, turbid water purifier, precipitant, color-fixing agent and filler.
