“…As verified by CV in Figure 3b, similar results were observed. The area of the CV cycles became larger in the order of PbO 2 -Ti > Pt > SnO 2 /Sb-Ti > Ti, which could be related the higher conductivity and catalyst activity of PbO 2 -Ti compared with the others [47]. This conclusion was confirmed by Tafel curves showed by Figure 3c.…”

To replace the high cost Pt anode, Ti based PbO2 electrode (PbO2‐Ti) and Ti based SnO2 doped with Sb electrode (SnO2/Sb‐Ti) were fabricated and compared for treating 0.1 mM Rhodamine B (RhB) in Electro‐Fenton (EF) process. Scanning electron microscopy, energy dispersive X‐ray, X‐ray diffraction spectrometry were carried out to study the surface morphology, element composition, and substance composition of the anodes (PbO2‐Ti and SnO2/Sb‐Ti). Linear Sweep Voltammetry, cyclic voltammetry, Tafel, and electrochemical impedance spectroscopy were conducted to examine the electrochemical properties of the anodes (Pt, PbO2‐Ti, SnO2/Sb‐Ti, and Ti). These assessments showed that PbO2‐Ti had the best performance. Then, the influence of varied parameters (pH, types of anodes, current density, and electrolyte) were explored. Almost complete decolorization (99.01%) was reached at pH 3, current density 50 A/m2, 0.05 M Na2SO4 using PbO2‐Ti as the anode after 20 min electrolysis. Under these conditions, 90.48% of total organic carbon was removed after 180 min. Finally, the durability of PbO2‐Ti was evaluated via accelerated service life test and exhibited long service lifetime (∼4000 h). © 2018 American Institute of Chemical Engineers Environ Prog, 38: 189–197, 2019

An electrochemical method for the determination of tripelennamine hydrochloride (TPA) using cetyltrimethylammoniumbromide‐multiwalled carbon nanotubes modified glassy carbon electrode (MWCNT‐CTAB/GCE) was developed. Because of good electrical conductivity of MWCNT and catalytic behavior of CTAB, new electrode significantly enhances the sensitivity for the detection of TPA. Parameters such as amount of modifier suspension, scan rate, pH of measure solution, heterogeneous rate constant were investigated. The electrode exhibits a linear potential response in the range of 1.0×10−8 M to 3.0×10−6 M with a detection limit of 2.38× 10−9 M. The modified electrode was successfully applied to the determination of TPA in pharmaceutical and real samples.
