Electro-oxidative Decolouration and Degradation of Amaranth Dye Wastewater in Batch Setup using Novel Ti/TiO2-Ru2O-IrO2 Anode

In this work, electro-oxidation of amaranth dye wastewater has been performed using dimensionally stable anode (DSA) and stainless-steel cathode. Ti/TiO2-Ru2O-IrO2 ternary electrode was used as the anode. Effect of various parameters such as current density, pH, voltage and time on the degradation and decolouration of dye was studied. Optimum conditions for the treatment of dye wastewater in batch setup were found. The complete decolouration was achieved in the first 5 min of the process. Decolouration and degradation of amaranth dye wastewater followed pseudo-first-order kinetics. The present research work unlocks the new horizon towards the degradation of dye wastewater employing the once through continuous process.

Manufacturing fine graphite powder with AC electric synthesis

There is presented a technology for manufacturing fine powder of graphite of GE type by means of synthesis. A device with the separation of anode and cathode area by means of Dacron diaphragm use is described. Basic elements of the installation are a stainless steel cathode and a graphite anode submerged into aqueous solution (electrolyte). As a result of the experiment there is obtained fine powder with an average graphite particle size of 4mkm.

Electronucleation mechanism of copper in wastewater by controlled electrodeposition analysis

To improve the efficiency of copper deposition in wastewater containing polyvinylpyrrolidone surfactant and reveal the mechanism of copper crystals, a controlled electrodeposition process was developed using a low-cost stainless steel cathode and electrochemical methods.
