Use of calcium peroxide to provide oxygen for contaminant biodegradation in a saturated soil

Properties of calcium peroxide for release of hydrogen peroxide and oxygen: A kinetics study

“…White et al [12] and Cassidy and Irvine [14] measured release of O 2 for 2 months in soils with unbuffered CaO 2 , but Ndjou'ou and Cassidy [1] indicated that CaO 2 was exhausted within 2 days at pH 8. Nykanen et al [33] reported that CaO 2 can release O 2 when it reacts with water over 5-7 months.…”

“…CaO 2 is one of the most versatile and safest solid inorganic peroxy compounds that can be considered as a solid form of oxygen [8,11]. The released oxygen can promote contaminant oxidation and enhance in situ aerobic microbial degradation [12][13][14][15]. Therefore, CaO 2 has been used for the remediation of many contaminated sites in US and in other developed countries [16].…”

“…White et al [12] reported that CaO 2 greatly stimulated microbial growth in an arctic soil contaminated by crude oil. Cassidy and Irvine [14] found that CaO 2 promoted aerobic bioremediation of a water-saturated silty loam contaminated by http bis-(2-ethylhexyl) phthalate (BEHP). Liu et al [13] used an oxygenreleasing material (CaO 2 ) to construct permeable reactive barrier system and successfully removed methyl tert-butyl ether (MTBE) from groundwater.…”

Multicatalytic properties of nanoparticle CaO2 synthesized by a novel, simple and economical method for wastewater treatment

“…H 2 O 2 would slowly release from CaO 2 in the presence of moisture. CaO 2 has been extensively used in medicine, aquaculture and agriculture [18][19][20][21][22]. Disinfectant for water treatment has been validated recently.…”

Performance of tetramethoxyphenyl porphyrin cobalt(II) (CoTMPP) based stainless steel cathode in the electricigenic permeable reactive barrier for groundwater organic contamination remediation

“…However, as well as their instability and costliness, peroxides have harmful effects on organisms contacting them for their inhabitation or toxicity (Cassidy & Irvine 1999), so there will be some security risk when using them.…”
