Aluminium Sulphate Standard: HG2225-2001 Molecular Formula: AL2(SO4)3 ? Properties: including anhydrous and hydrous(18 crystal water) type. Usually, the crystal separated out from aqueous solution at the normal temperature is Al 2 (SO 4 ) 3 .18H 2 O; when weathering, the average molecular structure is Al 2 (SO 4 ) 3 .14H 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.1984) is 0.036%; 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.State: flake or powder or lump Packing:PP/PE 50kg/bag Aluminum sulphate Re: Aluminum Sulphate 15.8% Appearance : White lumps/granules/ powder Specification: Al2O3: 15.8% min Fe: 0.45% max PH value: 3.0 min Water-insoluble Matter: 0.15% max As: 0.0005% max Pb: 0.002% max size:15mm max (granular) PH value: 3.0 min Water-insoluble Matter: 0.15% max As: 0.0005% max Pb: 0.002% max size:15mm max (granular) Re: Aluminium sulphate 16.0% Appearance : White lumps/granules/ power Specification: Al2O3: 16% min Fe: 0.4% max PH value: 3.0 min Water-insoluble Matter: 0.15% max As: 0.0005% max Pb: 0.002% max size:15mm max (granular) Re: Aluminium sulphate 17.0% Appearance : White lumps/granules/ power Specification: Al2O3: 17% min Fe: 0.3% max PH value: 3.0 min Water-insoluble Matter: 0.15% max size:15mm max (granular) Re: Aluminium sulphate17.0% Non Ferric Appearance : White lumps/granules/ power Specification: Al2O3: 17% min Iron: 0.01% max PH value: 2.6 min Water-insoluble : 0.5% max size:15mm max (granular)
