“…Thirdly, it is nontoxic at relatively high concentrations, which makes it suitable to determine • OH in some AOPs involving microorganism [18,19]. Fourthly, it is highly reactive with the hydroxyl radicals (k = 4.5 ∼ 7.1 × 10 9 mol L −1 s −1 ) forming methanesulfinic acid (MSA), methyl radicals and formaldehyde [20][21][22][23]:…”

“…In the past decades, methanesulfinic acid has been adopted for determination of hydroxyl radicals by spectphotometric method [20,21] and HPLC [22,23]. However, recent study [24,25] indicates that methanesulfinic acid is only an intermediate product, which also reacted rapidly with hydroxyl radicals leading to methanesulfonic acid and sulfate formation (k = 6.2 ∼ 12 × 10 9 mol L −1 s −1 ).…”

In this paper, a simple and sensitive method for the determination of hydroxyl radicals generated in advanced oxidation processes is described. The proposed method employed the reaction between hydroxyl radicals and dimethyl sulfoxide (DMSO) to generate quantitatively formaldehyde, which then reacted with 2,4-dinitrophenylhydrazine (DNPH) to form the corresponding hydrazone (HCHO-DNPH) and analyzed by liquid chromatography-UV. Factors affecting the derivatization reaction of HCHO and trapping reaction of hydroxyl radicals, as well as the applicability of the method, were investigated. The detection limit for hydroxyl radicals was 0.54 mol L −1 . The method had been used to determine the yield of hydroxyl radicals in various advanced oxidation processes (AOPs) to compare their oxidation ability.

“…Furthermore, the expensive instruments make it unsuitable for routine analysis. Another method is aromatic hydroxylation in which hydroxylate products arising from the reaction of ·OH with salicylic or benzoic acid are separated by high-performance liquid chromatography (HPLC) and detected by either electrochemical or UV detection [22,23,24,25]. Though this method is handy and sensitive, the multiple reaction products make the quantitative detection of ·OH complicated.…”

A simple and rapid electrochemical method to detect the hydroxyl radical is described. This method employed the reaction between.OH and dimethyl sulfoxide (DMSO) to generate quantitatively formaldehyde, which then reacted with hydrazine hydrochloride at pH 6.2. The product showed a second-order derivative cathodic wave with the peak potential of -1.08 V( vsSCE) by single sweep oscillopolarography. The electrochemical behavior of the product was investigated by single sweep oscillopolarography and cyclic voltammetry. The experimental conditions for the measurement were optimized and the scavenging activity of some flavonoids on hydroxyl radicals was studied.
