Recently oxalic acid leaching has been reported for early-stage recovery of Li from black mass (BM) of spent EV LIBs. Such processes often face challenges in electrodes separation, thermal treatment of cathode material, and leachate up-concentration. Herein, the synergistic application of benzoyltri...
Calculate the molarity of an aqueous oxalic acid solution, if a 10.00 mL sample of the oxalic acid solution requires 25.80 mL of 0.1573M NaOH to neutralize it in a titration. What is the mass of oxalic acid required...
Photocatalytic hydrogen evolution using oxalic acid as electron donor has been investigated over Pt–TiO 2 prepared by photodeposition. The reaction kinetics is consistent with the Langmuir model. The effects of pH, amount of deposited Pt and additives of inorganic anions on the rate of the reaction...
Due to the precipitation of salts such as Na2C2O4(s) and NaHC2O4(s) the NaOH-oxalic acid could act as pH buffer for the leaching. Such precipitation also reduces the concentration of the free bioxalate, HC2O4− required for the dissolution of iron oxide. KOH behaves the same as NaOH...
Alumina membranes were fabricated by anodizing aluminium metal in 0.15 M oxalic acid. The growth kinetics of the porous layer were investigated in the temperature range −1 to 16 °C using linear potential scans up to 70 V. The faradaic efficiencies of metal oxidation and of porous layer form...

The conversion values obtained for the oxidation of oxalic acid in 0.50M NaOH medium, on Pt/CNT, Pd/CNT and Ru–Cu/CNT modified electrodes, were respectively 42%, 60% and 85%. In this last medium, 88% of the initial oxamic acid (15.8mM) was transformed to carbonate ion and nitrogen ...
Selective precipitations of Zn and Mn from acid solutions were carried out using NaOH and KOH. Using 3M NaOH as precipitating agent at room temperature and at pH 8; 95.4% of Zn and at pH 10; 93.7% of Mn were precipitated from the leaching solution. Under the same conditions, using 3 ...
