The AirPLS algorithm was used to reduce the background interference signal, which was also amplified. The amplified Raman scattering effect of BA in the pickled vegetables displayed a positive and significant correlation with the HPLC concentration of BA, with high reproducibility. For HPLC ...
There was no detectable signal from the blank water sample using this transition. Although other endogenous basic compounds present in natural environmental sample were presumably coextracted and derivatized by PPIA reagent, no interference was observed due to the highly specific parent mass- to-charge...
Gazi S, Ananthakrishnan R (2012) Semi-quantitative determination of hydroxyl radicals by benzoic acid hydroxylation: an analytical methodology for photo-Fenton systems. Curr Anal Chem 8(1): 143-149. https://doi.org/10.2174/157341112798472297
Benzoic acid, here used as a chemical probe, gets hydroxylated to salicylic acid (SA) by the hydroxyl radicals, and the complex formed by SA with Fe3+ ions was measured spectroscopically. The formation of SA had increased with increase in the irradiation time, which indicates the progress of...
The esterification of anthranilic acid employing acid catalysis formed2as purple-colored oil with a 50% yield by procedure mentioned in the literature [12]. The absence of the O–H signal and the presence of a broad C=O signal in the IR spectrum indicated successful esterification. Although th...
