Possible Interaction: Hydrogen Peroxide and Citric Acid

“ Citric acid , a known antioxidant, scavenges hydrogen peroxide , a key intermediate using the uricase method.”

“Scavenging of hydrogen peroxide by citric acid competes for the leuco dye substrate.”

“Furthermore, the addition of exogenous CA can induce alternative oxidase (aox) gene expression under heat stress, reduce the content of H2O2 in mycelium, and consequently protect the mycelia under heat stress.”

“The citric acid promoted the production of H2O2 and Fe(II)/Fe(III) species, the degradation of protein in tightly-bound extracellular polymeric substances, and the decomposition of protein-N in the solid phase of sludge, resulting a greater conversion of bound water to free water.”

“Both EDTA and CA increased Cd-induced H2O2 production and lipid peroxidation.”

“The results revealed that the H2O2 bleaching can effectively improve the whiteness and also maintain a good anti-wrinkle performance of the CA treated fabrics under an appropriate bleaching temperature and time.”

“Batch tests with citric acid showed no signs of pressure accumulation and solid precipitations, however the results suggested that an excessive usage of H2O2 relative to iron catalysts (Fe2+/H2O2<1/330) would result in lowering the efficiency of contaminant removal by iron chelation in the citric acid system.”

“Adding alpha-tocopherol, citric acid , or a combination of the two compounds slowed the formation of hydroperoxides and their subsequent decomposition products in pH 3.0 emulsions.”
