Ammonium bisulfite solution (also ammonium bisulphite and bisulfite d'ammonium) is a clear light yellow liquid which can be used to remove entrained oxygen from drilling muds and completion fluids.systems.Comparing with sodium bisulfite, ammonium bisulfite is more water soluble and can react with oxygen faster. The overall reaction is: SO 2 + Na 2 CO 3 → Na 2 SO 3 + CO 2. If I know the amount of oxygen in such a solution, how can I know the required concentration of sodium sulfite to be used and react as oxygen scavenger? As an oxygen scavenger, Sodium Sulfite is added continually until the residual sulfite (SO3) concentration in the mud filtrate reaches or exceeds the levels required. This is important, because when you dispose of your pool water, it eventually makes its way back into rivers and oceans. Oxygen levels were reduced by the addition of the scavenger. The oxygen scavenger term is partially misleading because many of them mainly function as passivating corrosion inhibitors in addition to scavenging oxygen [1].
