Experimental and model comparisons of H2O2 assisted UV photodegradation of Microcystin-LR in simulated drinking water

Thermally activated persulfate (TAP) oxidation of antiepileptic drug carbamazepine in water

“…Furthermore, the generated Cl ÀÅ 2 and Cl Å could further react with itself to form Cl 2 and Cl À [31,32]. CO 2À 3 and HCO À 3 are the good scavengers for hydroxyl radicals, similar findings were reported everywhere [33]. In this study, CO 2À 3 and HCO À 3 both significantly inhibited the degradation rate of CBZ.…”

Factors affecting ultraviolet irradiation/hydrogen peroxide (UV/H2O2) degradation of mixed N-nitrosamines in water

“…First, the redox potential of hydroxyl radicals decreases when solution pH is increased; second, a high pH allows more carbonate and bicarbonate (alkalinity) present in water, which are well-known hydroxyl radical scavenger; third, a high pH could accelerate the self-decomposition of H 2 O 2 into water and oxygen (Eq. (4)) [21]. In Fig.…”

11 Control and management of harmful algal blooms

“…Hydrogen peroxide has been used occasionally for cyanobacterial management in WSPs, although there has been minimal scientiic investigation into the removal dynamics of cyanobacteria and cyanotoxins by this method. The addition of H 2 O 2 alone has often been considered inadequate for cyanotoxin treatment [140,165,170,174,228]. However, there are many physical, chemical and biological properties of WSPs that difer from laboratory studies, and the presence of such factors may improve the potential for cyanobacterial and cyanotoxin treatment by H 2 O 2 under WSP conditions.…”
