2020年2月15日 · Gamma-ray with the added H 2 O 2 and S 2 O 82− efficiently degraded CR. Reactivity of congo-red dye with OH and SO 4− were calculated. Proposed degradation pathways of CR were developed from the DPs evolved. Gamma radiation has received increasing attention due to their high potential in degradation of recalcitrant pollutants.

2015年12月15日 · Nonylphenol ethoxylates undergone gamma ray/H 2 O 2 treatment. Treatment efficiency was evaluated on the basis of degradation and toxicity reduction. A significant reductions in COD and TOC were achieved. Radiolytic by-products were low carbon carboxylic acids. AOP reduced the cytotoxicity and mutagenicity considerably.

2018年4月1日 · Hydrogen peroxide (H 2 O 2) is the only reasonably stable oxidizing species produced in the radiolysis of water and yet its fundamental behavior in water radiolysis is poorly known. Mechanisms for both the formation and reactivity of H 2 O 2 are important for advancing fundamental radiation science and for practical applications ( Buxton, 2004 ).

2001年12月14日 · The radiation chemical yield of hydrogen peroxide has been determined in the γ-radiolysis of water at neutral pH. Methanol, ethanol, and bromide have been used as OH radical scavengers in order to explore the temporal dependence of hydrogen peroxide formation at elevated temperatures.

2017年9月7日 · In this study, we first provide the experimental evidence that the 1 min of CAP treatment can trigger μM level cancer cell-based H 2 O 2 generation through comparing the H 2 O 2 generation in...

DNA strand breaks could be produced at dose levels of H2O2 much lower than those which induced CAs. Doses as low as 0.5 mM of H2O2 produced about as many DNA strand breaks as 2 Gy of 60Co gamma-radiation. On the other hand, as much as 20 mM H2O2 produced only half as many CAs as 1 Gy of 60Co gamma-radiation.

2019年8月20日 · The enhanced effect of gamma irradiation with hydrogen peroxide (H(2)O(2)) for alachlor degradation in an aqueous solution was first investigated in this study.

2010年5月15日 · The synergistic effect of gamma radiation with hydrogen peroxide (H(2)O(2)) for p-nitrophenol (PNP) decomposition in aqueous solution was evaluated. The PNP solution with initial concentration of 50mg/L was irradiated in the presence of extra H(2)O(2) at initial concentration of 0, 20, 40, and 80 mg …

The relative effectiveness of .OH, H2O2,O2−, and reducing free radicals in causing damage to biomembranes. Biochimica et Biophysica Acta (BBA) - Biomembranes 1981 , 640 (1) , 313-325.

Gamma radiation has received increasing attention due to their high potential in degradation of recalcitrant pollutants. Thus in the present study, gamma radiation was used for degradation of congo-red (CR) dye, a highly toxic and carcinogenic pollutant, in …
