“…Especially, as a preferred reactive site of SO4 •-, the amino and imino moiety was easily to be oxidized by SO4 •-and transformed as P-189 and P-269 . Ji et al (2015) and Yan et al (2011) also noted that SO4 •-was responsible for the formation of hydroxylated SMX. …”

Fenton or Fenton-like processes have been regarded as feasible methods to degrade a wide variety of contaminants by generating reactive species, but the efficiency is highly affected by the slow transformation from Fe(III) to Fe(II) as well as pH. This study proposed a method by adding hydroxylamine (HA) to the Fe(II)/HSO5 -(Fe(II)/PMS) process to accelerate the degradation of contaminants, selecting a broad-spectrum sulfonamide antibiotic -

“…4b). Yan et al (2010) reported that Fe 3 O 4 used at a high concentration hindered the PS oxidation of sulfamonomethoxine. In the present work, the high concentration of Fe 3 O 4 may have scavenged the SO 4 • − , leading to the transformation of the radical into the sulfate anion (SO 4 2− ).…”

“…However, currently only one study investigated the use of PS or activated-PS for the elimination of a different pharmaceutical product, sulfamonomethoxine (Yan et al, 2010). Although the activation of PS by soluble iron to form a sulfate radical (SO 4 • − ) has been previously reported, the initiation of PS decomposition by iron oxide minerals has been scarcely investigated (Ahmad et al, 2010;Yan et al, 2010).…”

The objective of this work was to evaluate the removal of ibuprofen (IBP) using the oxidants hydrogen peroxide (H 2 O 2 ) and sodium persulfate (Na 2 S 2 O 8 ). The ability of magnetite (Fe 3 O 4 ) to activate persulfate (PS) and H 2 O 2 for the oxidation of IBP at near neutral pH was evaluated as well. The use of soluble Fe 2+ to activate H 2 O 2 and Na 2 S 2 O 8 was also investigated. H 2 O 2 and Na 2 S 2 O 8 were inactive during the sixty-minute experiments when used alone. However, activation using Fe 2+ increased the removal to 95% in the presence of H 2 O 2 (Fenton reaction) and 63% in the presence of Na 2 S 2 O 8 at pH 6.6. Chemical oxygen demand (COD) removal was also greater for Fenton oxidation (65%) than for iron-activated PS oxidation (25%). Activation of H 2 O 2 and PS by Fe 3 O 4 was only observed at a high oxidant concentration and over 48 h of reaction time. A second order rate kinetic constant was determined for H 2 O 2 (3.0 * 10 − 3 M − 1 s − 1 ) and Na 2 S 2 O 8 (1.59 * 10 − 3 M − 1 s − 1 ) in the presence of Fe 3 O 4 . Finally, several of the degradation products formed during oxidation of IBP in the presence of H 2 O 2 and Na 2 S 2 O 8 (activated by Fe 2+ ) were identified. These include oxalic acid, pyruvic acid, formic acid, acetic acid, 4-acetylbenzoic acid, 4-isobutylacetophenone (4-IBAP) and oxo-ibuprofen.

This is due to (1) (Yan et al, 2011;Ghauch et al, 2013;Ji et al, 2014). Standard redox potential of SO 4 ¡ is C2.6 V, which is similar to OH with C2.72 V (Neta et al, 1988).…”

“…Standard redox potential of SO 4 ¡ is C2.6 V, which is similar to OH with C2.72 V (Neta et al, 1988). Sulfate radical-based advanced oxidation processes (SR-AOPs) are new methods to oxidize pharmaceuticals in water (Yan et al, 2011;Ghauch et al, 2013;Shah et al, 2013;Ji et al, 2014). In previous studies, Fe-activated persulfate has been used to remove pharmaceuticals.…”

Pharmaceuticals are detected at trace levels in waters. Their adverse effects on aquatic ecosystems and human health demand novel pharmaceutical removal technologies for treating wastewater effluents. Iron (Fe) or manganese (Mn) may play important roles in these new technologies since these metals are abundantly available at low costs and are known to contribute to organic conversions via physico-chemical, chemical, and biologically related processes. Few reviews describe and discuss Fe-or Mn-based technologies for the purpose to remove pharmaceuticals from water. Therefore, we review the current literature sorted into the three removal mechanisms, that is., through physico-chemical, chemical, and biological processes. The principals, performance, and influential parameters of these three types of technologies are described. Current and potential applications of these technologies are critically evaluated in order to identify advantages and challenges. In addition, the Fe-or Mn-based technologies which are currently not used but promising to further develop to remove pharmaceuticals cost efficiently are proposed.
