Effect of coating method on the structure and properties of a novel PbO2 anode for electrochemical oxidation of Amaranth dye

Reduced graphene oxide coated graphite electrodes for treating Reactive Turquoise Blue 21 rinse water using an indirect electro-oxidation process

“…The contact angle is an essential measure of the wettability of the surface of the graphite electrode. The higher is the contact angle, the lower becomes the tendency to wet the electrode surface with higher hydrophobicity [42]. From Fig.…”

Fabrication and characterization of titanium‐based lead dioxide electrode by electrochemical deposition with Ti4O7 particles

“…Further improvement is consequently required to promote the electrode performance. At present, alternative modification methods reported prevalently include surface modification, introduction of intermediate layer (Jia et al, 2019), selection of new preparation methods (Elaissaoui et al, 2019), matrix modification (Liu et al, 2018;Yao, Huang, Yang, Li, & Ren, 2018;Yingwu, Xin, Naichuan, Haishu, & Haoren, 2017), etc. Surface modification, using metal ions (Hao, Dan, Qian, Honghui, & Wei, 2014), F ions, surfactants (Hao et al, 2016;Xiaoyue, Feng, Yinan, Yawen, & Limin, 2018), and particles (Xie et al, 2017), is relatively more investigated among such many modification methods.…”

“…In addition, the possibility of lead ion release in the operation process of PbO 2 electrode brings about its incompetence for drinking water treatment; nonetheless, it has been widely studied and applied in the wastewater treatment field (Hao, Wei, & Honghui, 2015). Therefore, PbO 2 electrode has a remarkable application prospect in the field of electrochemical oxidation of wastewater (Duan, Sui, Wang, Bai, & Chang, 2019; Elaissaoui, Akrout, Grassini, Fulginiti, & Bousselmi, 2019; Jiani et al., 2020; Xie et al., 2017), whereas there are still some defects of PbO 2 electrode in terms of stability and catalytic ability, such as easy peeling off of the coating since low adhesion, lower electro‐catalytic efficiency for organic matters than Sb‐SnO 2 and BDD electrodes, and insufficient service life in the electrolysis process (Li et al., 2011). Further improvement is consequently required to promote the electrode performance.…”

A simple and sensitive approach for the electrochemical determination of amaranth by a Pd/GO nanomaterial-modified screen-printed electrode

“…[1][2][3][4] Therefore, U.S.A. has forbidden the use of amaranth in food, and China does not allow amounts of this additive in so drinks over the maximum limit of 0.05 g kg À1 (GB2760-2014). [5][6][7] Amaranth has recently been determined by numerous methods, namely spectrophotometry, 8,9 high performance liquid chromatography (HPLC), 10,11 thin layer chromatography (TCL), 12 electrochemical analysis, [13][14][15][16][17][18] uorescence, 19,20 colorimetry, 21 and electrophoresis. 22 Electrochemical method is superior to the aforementioned methods due to the excellent merits, e.g., easy operation, low cost, simple equipment requirement, and quick response.…”
