Removal of 2-MIB and geosmin using UV/persulfate: Contributions of hydroxyl and sulfate radicals

Degradation of oxcarbazepine by UV-activated persulfate oxidation: kinetics, mechanisms, and pathways

“…1, PS alone exhibited lowest OXC degradation rate compared to UV irradiation and UV/PS process, with approximately 2 % removal in 120 min. These results were consistent with the finding of Xie et al, who reported that UV irradiation alone and PS alone were inefficient for degradation of geosmin and 2-MIB (Xie et al 2015). It can be concluded that the combination of UV irradiation and PS significantly improved the efficiency of OXC degradation owing to the highly reactive radical species.…”

“…Unfortunately, the removal efficiency of OXC is quite low by both drinking water treatment plants and wastewater treatment plants, since most of them are not designed to remove pharmaceutical products (Li et al 2011). Hence, extra processes such as adsorption, oxidation, or ultrafiltration are required to handle certain pharmaceutical products (Xie et al 2015). Apart from these, advanced oxidation processes (AOPs) are also alternative Responsible editor: Roland Kallenborn Electronic supplementary material The online version of this article (doi:10.1007/s11356-015-5524-1) contains supplementary material, which is available to authorized users.…”

“…Among sorts of AOPs, UV-based oxidation has potential application possibility due to its high efficiency (Tan et al 2013;Xie et al 2015). Typical UV-based oxidation includes UV/H 2 O 2 and UV/ S 2 O 8 2− (PS).…”

“…Great quantity of previous studies have presented that UVactivated persulfate can effectively degrade a wide range of organic contaminants, such as MC-LR (Antoniou et al 2010a;Antoniou et al 2010b), taste and odor compounds (Xie et al 2015), pesticides (Luo et al 2015), and tetramethylammonium hydroxide (Wang and Liang. 2014).…”

Degradation of Acid Orange 7 in Aqueous Solution Under Presence of Iron(iii), Persulphate and Visible Light Irradiation

“…Recently, persulfate (PS, S2O8 2-) with a redox potential equal to 2.01 V [1], attracts high attention due to its easy storage and transport, high stability, high aqueous solubility, and comparatively low cost [2][3]. Extensive research works have been held on the activation of PS under: interaction of heat [4][5], base activation [6], ultraviolet (UV) light (sensitive wavelength 220-310 nm) [7][8][9][10] activation, ultrasound activation [11], and transition metals activation [12][13][14][15][16][17].…”
