Electro Osmosis

Water content and Strength of Dredged Soil (DS) obtained from Aliyar reservoir were measured after dewatering using Electro Osmosis (EO). The operational conditions adopted include electrode material (Cu, Fe, Al), voltage (6V, 12V, 24V) and duration (24 hours, 48 hours and 72 hours). 27 combinations of experiments were piloted to explore the influence of operational conditions on water content and strength in shear. Maximum reduction in water content was obtained in Fe electrode with 24V and 72 hours of duration for which the water content falls to 27.22% from 87% and the corresponding shear strength is 27.30 kPa. Further, the loss of electrode materials during EO process was also measured.

Preliminary Separation

Our objective was to develop a process for recovering acetyl groups from industrial northeast hardwood chips. Extraction experiments showed that the white liquor charge of 6% effective alkali at 50°C and liquor-to-wood ratio of 4:1 leads to the complete extraction of acetyl groups from industrial hardwood chips. Electrodialysis was assessed as a technique for separating and concentrating sodium acetate from synthetic hardwood extract. Preliminary separation experiments using dilute sodium acetate showed that the sodium acetate can be concentrated up to approximately 24% by weight from an initial concentration of about 2% by weight. The effects of current density, feed concentration, electro-osmosis, and osmosis on the separation of sodium acetate were evaluated. Finally, selectivity experiments were performed to study the effect of various components of the white liquor on the separation of sodium acetate. Fully oxidized synthetic white liquor was used in selectivity experiments to avoid deleterious effects of Na2S. Selectivity experiments using synthetic oxidized white liquor showed a significant decrease in the separation efficiency due to the presence of sodium hydroxide, sodium carbonate, and sodium sulfate in the synthetic extract.

Formic Acid Oxidation Reaction

In paper electrode materials with palladium nanoparticles on polymer matrix substrates for energy sources have been formed. Nanocomposites were investigated by atomic force and scanning electron microscopy. The catalytic activity of formed electrodes in the formic acid oxidation reaction was evaluated by voltammetry method.
