Iron free aluminum sulfate
Iron free aluminum sulfate
Iron-free aluminum sulfate is an inorganic compound (sulfate). The solid product is white granular or massive, with white shiny crystals. It is stable in the air, easily soluble in water, almost insoluble in ethanol, and the solution is acidic.
The main differences between low-iron aluminum sulfate and iron-free aluminum sulfate liquids are:
1. Appearance:
Low-iron aluminum sulfate liquid is odorless, hygroscopic, and has a density of 1.69 g/ml (25°C).
Iron-free aluminum sulfate is a solid product in the form of white granules or blocks with density of 2.7g/ml
Simply saying, the low-iron aluminum sulfate it's appearance is off-white with a little green,while the iron-free aluminum sulfate is pure white.
2. Purpose:
Low-iron aluminum sulfate liquid is mainly used in papermaking and water purification, and is used as a mordant, tanning agent, medicinal astringent, wood preservative, foam fire extinguishing agent, as well as an effective cross-linking agent for animal glue and a curing agent for urea-formaldehyde glue.
Iron-free aluminum sulfate is used in papermaking, specialty water treatment, titanium dioxide production and fillers.
Low-iron aluminum sulfate liquid involves drinking water. Aluminum sulfate is a professional drinking water treatment agent for purifying low-temperature, low-turbidity natural water sources. It can effectively remove impurities such as suspended solids, colloids, algae, sediment, and heavy metals in natural water sources. It is mainly used in raw tap water purification treatment and is also widely used in the food processing industry.
Generally speaking, the difference between the two mainly lies in appearance and purity. We can choose high-purity iron-free aluminum sulfate or low-purity low-iron aluminum sulfate liquid according to the actual needs of different industries.
