Barium carbonate treatment of sulfuric acid wastewater
Two methods of removing sulfates from sulfuric acid wastewater through the addition of barium carbonate and the formation of a barium sulfate precipitant were investigated. Optimization of barium carbonate dosage, reaction time and mixing conditions was accomplished for each method prior to …

Liquid-liquid extraction of rare earth elements from sulfuric acid
This thesis is concerned with the liquid-liquid extraction and separation of Y, Ce, La, binary mixtures, and ternary mixtures as well as synthesis of novel amide ligands for the extraction of rare earth elements. Chapter I is the general introduction of the practical process and applications of …

The Formal Redox Potential of the Permanganatemanganous System in Sulfuric Acid
… of the permanganate-mangonous system in sulfuric acid. All investigations undertaken were to secure more accurate standard potentials for the manganous-manganese dioxide system and the manganese dioxide-permanganate system in order to calculate the thermodynamic oxidation potential of the …

Hydrometallurgical processing of nickel sulfides with activated carbon in sulfuric acid medium
… strongly acidic and oxidative environments. Sulfuric acid was selected as the principal lixiviant due to its industrial relevance, while ferric ions were identified as a critical oxidant facilitating sulfide mineral breakdown. Sequential extraction and batch leaching experiments demonstrated …

Wet-spinning of neat single-walled carbon nanotube fiber from 100+% sulfuric acid
… the first time, it has been reported that liquid sulfuric acid forms shell structure while exposed to SWNTs.

Geochemical and mineralogical impacts of sulfuric acid on clays between pH 5.0 and -3.0
… mine drainage systems at pH > 1.0. The impact of sulfuric acid leachate characterized by pH < 1.0, including potentially negative pH values on the geochemistry and mineralogy of clays is, however, not clear. To address this deficiency a series of batch and diffusion cell studies, investigating the …

Electropolishing of Niobium in Sulfuric Acid-Methanol Electrolytes: Development of Hydrofluoric Acid-Free Electrolytes
… project, HF-Free EP of Nb was performed in sulfuric acid-methanol electrolytes. Sulfuric concentrations of 0.1 M, 0.5 M, 1 M, 2 M, and 3 M were used. Cyclic voltammetry and potential hold experiments were performed in cells of both two-electrode and three-electrode setups to evaluate the …

Heats of Neutralization of Sodium and Potassium Hydroxides with Sulfuric and Hydrochloric Acids Measured in an Ice Calorimeter
The heat evolved when a strong acid and a strong base react together in dilute solution affords a test in favor of Hess’s theory of ionization. In the case of the interaction of HC1 with KOH, or NaOH, in solution there is a remarkably close agreement among the values of deltaH. The average value is …
