Direct UV photolysis of propranolol and metronidazole in aqueous solution

Facile synthesis and high activity of novel BiVO4/FeVO4 heterojunction photocatalyst for degradation of metronidazole

“…Continuously increasing consumption and emission (incomplete absorption and metabolism) of metronidazole drugs will lead to its accumulation in organisms and environment. Even more importantly, it may pose health risks to humans [39,40]. Due to its widely used, highly soluble, nonbiodegradable and suspectedly carcinogenic, more attention has been paid to the environmental impact and health risks caused by metronidazole [41].…”

Heterogeneous catalytic ozonation by Nano-MgO is better than sole ozonation for metronidazole degradation, toxicity reduction, and biodegradability improvement

“…Due to low biodegradability [4], high toxicity [7], high solubility, and resistant character [9], its removal from water and wastewater is difficult. However, it can be removed via methods such as biological methods [10], sorption [11], oxidation processes [12], physical methods [13], application of nanoscale zero-valent iron [4], and advanced oxidation processes (AOPs) [8]. Rivera-Utrilla et al have studied the removal of nitroimidazole antibiotics from aqueous solution by adsorption/bioadsorption on activated carbon, and he concluded that the presence of microorganisms increases nitroimidazole antibiotics adsorption/bioadsorption on the activated carbon.…”

Efficient degradation of lindane in aqueous solution by iron (II) and/or UV activated peroxymonosulfate

“…Lindane does not contain UV absorbing chromophore functional groups [41][42][43]. It is thus not surprising to observe only limited photolysis of lindane by UV only, as shown in Figure 2.…”
