An exhaustive whitepaper on the chemical thermodynamics, performance parameters, and industrial customization of Al2(SO4)3.
Aluminum Sulphate ($Al_2(SO_4)_3$, CAS Registry Number 10043-01-3), commonly known as papermaker's alum or filter alum, is a critically important chemical compound utilized globally. Depending on its hydration state, it typically manifests as a crystalline solid or white powder, or as a liquid solution when dissolved in water.
Its industrial-grade forms are categorized by their iron content: Iron-Free Aluminum Sulphate (containing less than 0.005% $Fe_2O_3$) and Low-Iron/Industrial Aluminum Sulphate (containing up to 0.50% $Fe_2O_3$). The chemical efficiency of Aluminum Sulphate depends primarily on its active alumina ($Al_2O_3$) concentration, which governs its capacity for charge neutralization and sweep coagulation when dissolved.
| Property Parameter | Iron-Free Solid Grade | Liquid Industrial Grade | Test Standard Compliance |
|---|---|---|---|
| Alumina ($Al_2O_3$) Content | ≥ 17.00 % | ≥ 8.00 % | GB/T 1893-2008 / AWWA B403 |
| Iron ($Fe$) Content | ≤ 0.005 % | ≤ 0.20 % | ICP-OES analysis |
| Water Insoluble Matter | ≤ 0.15 % | ≤ 0.20 % | Gravimetric Method |
| pH Value (1% aqueous solution) | ≥ 3.0 | ≥ 2.5 | Electrometric method |
| Heavy Metals ($Pb$) | ≤ 0.001 % | ≤ 0.002 % | US Food Chemicals Codex (FCC) |
