“…Therefore, as a first approximation, the analytical concentration of GLYCA can be used in the place of glycolate ion while calculating the [Complex 1]. Substituting for the concentrations of Complex 1, from reactions (6) to (8), in equation (16) we get expression (17).…”

The kinetics of oxidation of glycolic acid, an α-hydroxy acid, by peroxomonosulfate (PMS) was studied in the presence of Ni(II) and Cu(II) ions and in acidic pH range 4.05-5.89. The metal glycolate, not the glycolic acid (GLYCA), is oxidized by PMS. The rate is first order in [PMS] and metal ion concentrations. The oxidation of nickel glycolate is zero-order in [GLYCA] and inverse first order in [H + ]. The increase of [GLYCA] decreases the rate in copper glycolate, and the rate constants initially increase and then remain constant with pH. The results suggest that the metal glycolate ML + reacts with PMS through a metal-peroxide intermediate, which transforms slowly into a hydroperoxide intermediate by the oxygen atom transfer to hydroxyl group of the chelated GLYCA. The effect of hydrogen ion concentrations on k obs suggests that the structure of the metal-peroxide intermediates may be different in Ni(II) and Cu(II) glycolates. C

“…The 2,4-D contaminated solution of 100 mg/L (0.452 mM) was prepared. Note that through a literature survey, the 2,4-D concentration range of 22-230 mg/L was commonly found in surface and ground water at 2,4-D contaminated sites (Sun and Pignatello 1993;Brillas et al 2000;Jackman et al 2001;Kwan and Chu 2003;Bandala et al 2007). A fixed SPS concentration of 100 mM and different activator concentrations of 300 mM H 2 O 2 , 50 mM NaOH, and 10 mM Fe 2?…”

This paper reports an investigation of different persulfate (PS) activations, including PS at 20°C (PS), thermally activated PS at 70°C (T-PS), ferrous-ion activated PS at 20°C [Fe(II)-PS)], hydrogen peroxide activated PS at 20°C, and sodium hydroxide activated PS at 20°C, for degradation of the herbicide 2,4-dichlorophenoxyacetic acid (2,4-D) in aqueous phase. Several findings were made in this study including the followings: the 2,4-D degradation rates in T-PS and Fe(II)-PS systems were higher than other systems. However, complete degradation of 2,4-D and associated derivatives can be reached in all oxidation systems, with various reaction times. When considering the results of PS consumption during the 48 h reaction time to reach complete 2,4-D degradation, the T-PS system consumed all of the PS while only 10 % of the PS was consumed in the Fe(II)-PS system.
