The more accurate jL or the contribution of charge transfer could be derived from the Koutecky-Levich equation [61] in the RDE measurements. Because the net rate of the anodic reaction (i.e., copper corrosion) must equal the net rate of the cathodic reaction (i.e., mainly oxygen ...
Powders of the raw material were used in the form of a dispersed (solid) phase in the hydrochloric acid electrolyte (liquid phase). In all experiments, the volume of the electrolyte was 350 mL, and the concentration of the hydrochloric acid was 6 M. The choice of the electrolyte ...

Changes in the permeate flux over time during copper ion removal in the presence of the ABSNa50 anionic surfactant (5 CMC) as a function of hydrochloric acid concentration are presented in Figure 10b. During the process, the permeate flux decreases much more at the beginning of the filtration...
CuSO4 (≥99.0%), poly(allylamine hydrochloride) (PAH, Mw~17500), L-ascorbic acid (LAA), hydrochloric acid (HCl), amino acids, and EDTA were purchased from Sigma-Aldrich (St. Louis, MO, USA). DFX (98%) was purchased from Toronto Research Chemicals (North York, Canada). Other metal ...
using a one dimensional Fourier law as shown in Equation (1), where𝑑𝑥dxis the distance between each thermocouple,𝑑𝑇dTis the temperature difference,𝜆𝑐λcis the copper thermal conductivity andqthe heat flux. The total amount of heat flux was determined by the average of the five...
The dissolution of copper telluride in alkaline solution may be represented by the following Equation (1): Cu2Te + 2NaOH + 2O2 = 2CuO + Na2TeO3 + H2O (1) From Equation (1) it is observed that 1 mole of tellurium will require 2 moles of alkali. Considering the tellurium content it...
The layer protection performance (P%) calculated with Equation (3), has maintained at a high level, very close to the one calculated from the EIS, meaning that during the impedance measurements, very limited desorption process of PVBA took place and consequently, the polymer molecules are strong...
