Ion price of titanium suboxide surface (40.84 ). As shown in Figure 7b, the LVX conversion rate of titanium suboxide reached one hundred . The removal and conversion prices of LVX are substantially greater than that with the ruthenium itanium electrode, indicating that the titanium suboxide electrode has a lot improved electrochemical performance than the industrially produced rutheniumtitanium electrode. For the EPR test, spin trapping was employed on 5,5-dimethyl-1pyrroline-1-oxide (DMPO) as a hydroxyl-radical scavenger (Figure 7e). As the reaction progresses, the intensity of hydroxyl radicals steadily increases. three.7. Exploration of CFT8634 site Degradation Mechanism Tert-butyl alcohol (TBA) has been frequently adopted as a quenching agent for hydroxyl radicals ( H). Hence, herein, TBA was added to the technique below study to elucidate the degradation mechanism. In this reaction, active chlorine mainly stems from NaCl added inside the reaction. Figure 7c shows that after adding TBA, the TOC removal and also the LVX conversion price decreased, indicating that H influenced the degradation of LVX. Active chlorine has a advertising impact around the conversion and mineralization of LVX when NaCl will not be involved inside the reaction (Equations (four)six)) [16]. Figure 7d shows that when NaCl was absent, the removal price of TOC and also the conversion price of LVX decreased additional, so it was speculated the active chlorine significantly influences the degradation of LVX, followed by H. 2Cl- Cl2 + 2e- (five)Components 2021, 14,13 ofCl2 + H2 O HClOHClO + Cl- + H+ ClO- + H+ .(six) (7)Figure 7.

Probable Degradation Routes of LVX To additional disclose the degradation mechanism, the intermediate merchandise of LVX degradation in the electrooxidation method had been identified using LC S. Figure eight displays the MS spectra of detected degradation intermediates. Furthermore, 5 plausible degradation routes of LVX have been proposed (Figure 8) as outlined by the intermediates. In pathway I, the hydroxylation reactions cause the production of L1 (m/z = 379). L6 (m/z = 337) was formed by decarboxylation of L1 (m/z = 379). In pathway III, in line with this, the molecular ion peak underwent a decarboxylation reaction of the methyl morpholine group in the LVX drug and was transformed into L3 (m/z = 333). Then, the decarboxylation and despiperazine groups of L3 (m/z = 333) result in the production of L10 (m/z = 250). In pathway IV, L4 (m/z = 278) was initially formed via an attack on the N-methyl piperazine group by reactive radicals ( H) and active chlorine. L4 (m/z = 278) was converted to L10 (m/z = 250) by decarboxylation. In pathway V, L5 (m/z = 317) was made by way of the decarboxylation of LVX. In addition, L14 (m/z = 163) was obtained by demethylation, decarboxylation, and despiperazine groups of L5. In pathway II, the demethylation and hydroxylation reactions cause the production of L2 (m/z = 363). L7 (m/z = 335) was formed by the decarboxylation of L2 (m/z = 363). Also, L6 (m/z = 337) could possibly be obtained by breaking the double bond of L7 (m/z = 335). L7 (m/z = 335), the crucial intermediate of LVX, was additional degraded on the.
