сульфат алюминия <Al2 (SO4) 3>

aluminium sulphate Quality indexQuality(Al2O3)%15.6%-17%(Fe)%0.5%-0.005%Water Insoluble %≤ 0.15% PH(1%water solution)≥3.0 Specification: ferric aluminium sulphate Aluminium oxide Al2O3 % min 16.0 % Iron Fe content% max 0.5% Water insoluble matter 1% max 0.15 % PH value 1% aqueous solution min 3.0 Heavy metals as Pb % max 0.002 % AS % max 0.0005% Size:10mesh-100mesh; Application:Alumina is often as flocculant for purification of drinking water and sewage treatment equipment of, also used in papermaking industry. Alumina is also used to adjust soil pH value, because it also generate aluminum hydroxide hydrolysis produce a small number of sulfuric acid dilute solution.
