Aluminium Sulphate

Description

Aluminium Sulphate Standard: HG********1 Molecular Formula:AL2(SO4)3 Properties: including anhydrous and hydrous(*8 crystal water) type. Usually, the crystal separated out from aqueous solution at the normal temperature is Al 2 (SO 4 ) 3 .*8H 2 O; when weathering, the average molecular structure is Al 2 (SO 4 ) 3 .*4H 2 O, may appear white powdery, with bright flake or crystalline flakelet, odorless, to change the taste from sweetness to slight astringency. Uses: solidifying agent(to purify grease and water) and stabilizer in pasteurization of albumin(including: liquid or refrigerated whole egg, egg white or egg yolk), the maximum allowable use level(FAO/WHO.***4) is 0.**6%; Used in papermaking , printing and dye , tanning leather , fire-fighting equipment , drug and wood preservation , etc; Treatment for the drinking water and water for industrial use.
