Determination of catalytic oxidation products of phenol by RP-HPLC

Abstract

A reversed-phase high-performance liquid chromatography (RP-HPLC) with ultraviolet detection was established for the determination of phenol, catechol, hydroquinone, and p-benzoquinone in the reaction solution of catalytic oxidation of phenol using hydrogen peroxide as the oxidant and copper-doped FeSBA-15 zeolite as the catalyst. Separation was accomplished on a reversed-phase C 18 column, and the elution condition was optimized by changing the composition of the mobile phase. A good resolution of all of the relative components in the reaction solution was achieved when the mobile phase was methanol-water-1% acetic acid aqueous solution = 10:50:40 (v/v/v). The concentrations of phenol, catechol, hydroquinone, and p-benzoquinone were determined in 11 different reaction solutions by the external standard method. The proposed HPLC method was simple, accurate, reliable, and suitable for tracing the amount of target products during the catalytic oxidation reaction of phenol. The results can provide data support for evaluating the

Enhanced Photocatalytic Performance for the BiPO4–x Nanorod Induced by Surface Oxygen Vacancy

“…At 5.3 min the product is phenol, and based on steric effect, those at about 2.7 min are 4,4′-dihydroxybiphenyl and 4-phenoxyphenol. , Others are intermediates, HQ (2. Five min), P-BQ (3.1 min), and catechol (3.8 min), respectively. − The peak of phenol disappears more quickly in vacancy BiPO 4– x than that in pure BiPO 4 . Furthermore, peaks attributed to degradation intermediates increase and then decrease in the vacancy BiPO 4– x system, while in pure BiPO 4 there was hardly any reduction.…”

Sensitive rGO/MOF based electrochemical sensor for penta-chlorophenol detection: a novel artificial neural network (ANN) application

“…[5][6][7][8] However, they are expensive and time-consuming, need a skilled operator, and are hard to implement. 9,10 Alternatively, spectrophotometry has been investigated for 5-CP sensing. 11 Despite their simplicity, speed, and low cost, the spectrophotometry-based methods gravely lack the selectivity.…”

Electrochemical Degradation of Phenol and Resorcinol Molecules through the Dissolution of Sacrificial Anodes of Macro-Corrosion Galvanic Cells

“…Electrooxidation trials were performed for selected synthetic wastewater compositions. Monitoring of phenol/resorcinol decomposition processes (along with a quantitative evaluation of possible reaction products) was performed by means of commonly used, instrumental HPLC/MS analysis [22][23][24], in function of electrolysis time.…”
