Sulfuric acidNRTL equationAbsorption.The success of flowsheeting systems in modeling chemical processes is fundamentally dependent upon their ability to adequately represent the physical properties and thermodynamic quantities of the chemical system of interest. The nonideal H2SO2 and H2O system poses ...
At the age of 28, 90, 120, and 180 days, three replicate cubes from each mix design were removed from the acid and water baths for the compressive strength test and weight loss measurement. The reduction in compressive strength (RCS) was calculated using the following equation: RCS=A−...
The batch leaching experiments were performed in a 200-mL round-bottom glass reactor, equipped with a thermometer. The leaching solutions were prepared by adding a predetermined amount of reagents into the solvent (isopropanol or water). In the reactor, a predetermined amount of sulfuric acid and...
In the process of leaching the cathode material of spent lithium-ion batteries, oxalic acid can be used as both a leaching agent and a reducing agent [29]. This is because oxalic acid is a kind of strong acid in organic acids, which can ionize part of the H+ ion. At the same time...
