Electrochemical degradation of reactive brilliant red X

2016/5/1Those images indicated that in electrolysis the (CeO 2 /C)-β-PbO 2-PTFE composite electrodes had higher activity than the β-PbO 2-PTFE electrodes, as good as the excellent catalytic performance. In the electrode system the composite electrodes were applied to treat reactive brilliant red (RBR) X-3B solution and we studied the degradation influence factors and the reaction mechanism.

Degradation of textile dye C.I. Vat Black 27 by

2013/12/1The electrolysis of dye solution was carried out at different current densities (85, 170, 255, 340 and 425 A m −2) at graphite carbon electrodes to investigate the influence of current density on the degradation efficiency of C.I. Vat Black 27 keeping NaCl concentration at 25 g/L, dye concentration at 50 mg/L, pH at 9 and temperature at 300 K.

Electrolytic Cells

The Electrolysis of Molten NaCl An idealized cell for the electrolysis of sodium chloride is shown in the figure below. A source of direct current is connected to a pair of inert electrodes immersed in molten sodium chloride. Because the salt has been heated until it

What are the factors affecting the product of

Electrolysis with inert electrodes like Platinum, graphite etc. Inert electrodes dos not react with the electrolyte or the products and so does not under go any changes. Since, oxidation of water has more positive potential, oxygen will be evolved at the anode.

A novel electro

A unique electro-chlorination reactor was designed with six numbers each of cylindrical shaped graphite anodes and stainless steel cathodes. A series of experiments were run in the laboratory scale applying lower current densities. Maximum active chlorine concentration of 0.75 mg/l was obtained at an optimum current density of 1.5 mA/cm2 from an available chloride concentration of 8.5 mg/l

Electrolysis of Sodium Chloride

Electrolysis of sodium chloride is an important process to manufacture many bulk chemicals of commercial utility, like chlorine, sodium hydroxide etc. Sodium chloride is electrolyzed either in a molten state or in aqueous solutions. Electrolysis is, also done in the

Electrolysis was carried out in an undivided cell, equipped with graphite electrodes as the anode and reticulated vitreous carbon (RVC) as the cathode, in acetonitrile as a solvent in the presence of NaI as a mediator and NaBF 4 as an electrolyte, under a

Hydrogen generation by water electrolysis using carbon

2010/5/1Anode made of multiwalled carbon nanotubes (MWNT) results in enhancement of exchange current density compared to graphite anode in a conventional alkaline water electrolysis cell. The hydrogen production rate with the nanotubes was measured to be ∼375 lh −1 m −2 at pH ∼ 14 which was nearly double of that obtained from traditional graphitic carbon electrodes at the same overpotential.

2020/11/1When two inert graphite electrodes are used in the electrolyte copper sulfate, how come oxygen is oxidised at the anode rather than the sulfate ions? Or could someone please answer this question: Explain why a different product is formed at the anode when copper sulfate solution is electrolysed using graphite electrodes rather than copper electrodes.

Question 16: During the electrolysis of aqueous copper sulphate, between copper electrodes, the sulphate and hydroxyl ions remain as spectator ions. Answer: During electrolysis of aqueous copper sulphate using copper electrodes, the two anions OH – .and S0 4 2- migrate to the anode, but none of them get discharged because the copper of the anode dissolves in the solution producing copper

To confirm, repeat the experiment first with copper electrodes then with your graphite electrodes but ensure that only the graphite is in the solution (so get rid of the tubes). If using the copper elecrodes gives the same result as above (blue green stuff) while using the graphite electrodes just gives O2 and H2 it means that the above theory is likely.
