Sodium metabisulfite containing more than 65.0% SO2 w/w releases sulfur dioxide gas when mixed with water. It forms a bisulfite adduct with aldehyde and with ketones to a sulfonic acid. It is used to purify or isolate aldehydes and ketones. Applications: 1. It is used as an oxygen scavenger to eliminate the dissolved oxygen in waste water and in pipes. 2. Bisulfite is a reductive bleaching agent. 3. It reduces carbonyl and alcohol groups, which function as colorants of the substances. 4. It is used in bleaching mechanical paper pulp, cotton, wool and kaolin clay. 5. Additional applications include as a preservative (antioxidant), a hair waving agent, and Ensiling agent. Packing: 25kg P.P Woven bags, 20MT in the 20’FCL
