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.

Design and Operation of First Egyptian IEC Fusion Plasma Device

In this paper, Egyptian first inertial electrostatic confinement fusion (IECF) device, constructed at the Egyptian Atomic Energy Authority (EAEA-IEC), is introduced the characterization of IEC Plasma Device. It consists of 2.8 cm stainless steel cathode, 6.5 cm anode diameter with 10 cm diameter 30 cm height vacuum chamber. The discharge current and voltage of plasma discharge has been recorded using current probe and resistive voltage divider respectively. The X-ray emissions in IEC plasma device were investigated by employing time-resolved detector. The temporal distributions of detected x-rays emission are occurring during the initial 1 microsecond. The calculated rate of DD-neutron generation using the same electrode configuration about 106 – 108 neutrons/second.

Effect of electric potential on the morphology and chemical composition of hollow fiber membrane surface in alkaline medium

The impact of electric potential on the dimensional characteristics and membrane surface morphology was investigated in this work. Our study samples comprise hollow fiber (HF) Polysulfone (PS) membrane. Conductive additives have been incorporated within the membrane matrix at the desired predefined concentration. The DC operated electrochemical apparatus consists of graphite anode and stainless steel cathode. The voltage and current density ranges are 2 to 10volts and 0.01 to 1.4mA/mm2 respectively. These investigations have been conducted in alkaline medium at pH=8.5. The results of this work revealed essential changes of hollow fiber (HF) dimensions, including external (DO), internal (DI) and membrane thickness (t). The maximum decrease of DO, DI, and t were 13%, 15%, and 11% respectively at 5volts. EDX analysis showed the maximum sodium ions of about 0.84% on the membrane surface at 2.5volts after 1-hour treatment.
