The Difference Between Low Iron Aluminum Sulfate Liquid And Iron Free Aluminum Sulfate

Low iron aluminum sulfate liquid is an inorganic substance with the chemical formula Al2 (SO4) 3, a formula of 342.15, and a density of 1.181g/ml (25 ℃). Iron free aluminum sulfate is a white crystalline substance that is easily soluble in water and insoluble in alcohol. The aqueous solution is acidic, and the dehydration temperature is 86.5 ℃. When heated to 250 ℃, the crystalline water is lost. Anhydrous aluminum sulfate begins to decompose when heated to 300 ℃. Anhydrous substance is a white crystal with a pearl like luster. But for many users, they are unaware of the differences between them. Next, let's take a closer look at the different performance aspects of these two.
The difference between low iron aluminum sulfate liquid and iron free aluminum sulfate is mainly compared from two aspects: characteristics and uses:
1, Traits:
Low iron aluminum sulfate liquid is odorless, hygroscopic, and has a density of 1.69 grams per milliliter (25 ℃). Iron free aluminum sulfate is a solid product, white in granular or block form, with a density of 2.71 grams per milliliter. The common understanding is that the former is gray white with a hint of green, while the latter is pure white.
2, Usage:
Low iron aluminum sulfate liquid is mainly used for paper making and water purification, as a mordant, tanning agent, medicinal astringent, wood preservative, foam fire extinguishing agent, effective crosslinking agent of animal glue and curing agent of urea formaldehyde glue. Iron free aluminum sulfate is used in papermaking, special water treatment, titanium dioxide production, and fillers.
Low iron aluminum sulfate liquid involves drinking water. Aluminum sulfate is a professional drinking water treatment agent that purifies low-temperature and 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 for the purification treatment of tap water raw water and is also widely used in the food processing industry.

Overall, the main difference between the two lies in their morphology and purity. Different industries can choose high-purity iron free aluminum sulfate or low-purity low iron aluminum sulfate liquid according to actual needs.
