The research results were published in《Separation and Purification Technology》 in 2020.Reference of 4-(2-Phenylpropan-2-yl)phenol The article conveys some information:
TiO2 photocatalysis and peroxymonosulfate (PMS) oxidation can exhibit a good performance in UV light but a less activity in visible light (VL). Herein, the TiO2 nano-tubes arrays (TiO2NTAs) and PMS were combined to degrade bisphenol A (BPA) under VL irradiation Surprisingly, about 94.6% of BPA was removed in TiO2NTAs/PMS/VL system within 30 min, which was much higher than that of TiO2NTAs/VL (20.1%) and PMS/VL (9.4%) systems. A series of spectroscopic characterizations and photoelectrochem. measurements confirmed the formation of PMS-TiO2 complex with VL response, which can be excited by VL to transfer electrons to the conduction band (CB) of TiO2 for activating PMS. The quenching tests and ESR (ESR) spectra indicated that SO·-4 and ·OH were responsible for BPA degradation, and then the possible degradation pathways of BPA were proposed. Humic acid (HA) and chloride ions (Cl–) significantly enhanced the BPA degradation, while bicarbonate (HCO–3) and phosphate (H2PO–4) exhibited an inhibition effect. Moreover, TiO2NTAs/PMS/VL system displayed an enhanced BPA degradation in tap water and drinking water compared with deionized water, and as an immobilization catalyst which fabricated on Ti plate, TiO2NTAs exhibited excellent stability and separability without complex catalyst separation/recovery processes. We believe this work will provide a new insight of the VL-induced photocatalytic PMS activation in practical water treatment. The experimental procedure involved many compounds, such as 4-(2-Phenylpropan-2-yl)phenol (cas: 599-64-4) .
4-(2-Phenylpropan-2-yl)phenol(cas:599-64-4) is a natural product found in Panax ginseng.Reference of 4-(2-Phenylpropan-2-yl)phenol 4-(2-Phenylpropan-2-yl)phenol is a useful reagent for preparing and characterizing aromatic polyphosphonates as high refractive index polymers.
