Chemical oxygen scavengers: use of hydrazine and tannins for boiler water treatment

On the formation of superoxide radicals on colloidal ATiO3 (A = Sr and Ba) nanocrystal surfaces

“…Hydrazine has been used to remove O 2 in industrialscale reactors for decades. 53,54 The reaction between hydrazine and O 2 produces N 2 and 2H 2 O, which provides the inert atmosphere during synthesis as shown in Scheme 1. 34 Post-synthetic attempts to control the concentration of defects on the surface of the SrTiO 3 NCs prepared by method-I were also performed.…”

Early-onset, conjugal, twin-discordant, and clusters of sporadic ALS: Pathway to discovery of etiology via lifetime exposome research

“…He had used “solvents: nitro-compounds and dimethylketone.” Prior to their diagnoses, both had engaged in various jobs including, between 1989 and 1993, the collaborative maintenance and operation of a gasoil-powered central heating system that served the apartments of the house in which they resided. Their chemical exposure during this period was unstated, but it is of potential interest that hydrazine solutions are used to control oxygen corrosion in boiler systems ( Scrivenand and Winter, 1978 ).…”

Oxygen scavenging activity of smart colophony microcapsules containing nitrite corrosion inhibitors for steel reinforced concrete

“…The colophony microcapsules with alkaline release will allow for mitigation of corrosion inhibitor loss during the concrete mixing stage, due to leaching and premature reaction with the binder by controlling the diffusion of the inhibitors, allowing release once the concrete cures to a highly alkaline pH (~12.6) (P. Kumar Mehta and Paulo J. M. Monteiro, 2014). Additionally, abietic is similar to tannins, which have been shown to decrease dissolved oxygen, in aqueous environments, thus acting as an oxygen scavenger (Scrivenand and Winter 1978).…”
