Description

Aluminum sulfate is a widely used industrial reagents, often confused with alum. Aluminum sulfate is usually used as a flocculant for purifying drinking water and wastewater treatment equipment, which is also used in paper industry. Under natural conditions, with little aluminum sulfate without water and salt form. It will form a series of hydrates, in which *6 water, aluminum sulfate is the most common. Aluminum sulfate is also a very effective insecticide mollusks that can kill the Spanish slug (Spanish slugs). Aluminum sulfate used in water purification and in textile dyeing and printing as a medium. In water purification, it makes impurities condensed and easier to sedimentation and filtration. When dissolved in a large number of neutral or slightly alkaline water, the resulting precipitate of aluminum hydroxide gel, Al (OH) 3. In the printing and dyeing fabrics, the dye aluminum hydroxide gel makes it easier to attach to top of plant fiber. Aluminum sulfate is also used to adjust the soil pH, because it is hydrolyzed aluminum hydroxide generated at the same time generate a small amount of dilute solution of sulfuric acid.
