The Canadian Journal of Chemical Engineering, EarlyView.Abstract This study proposes a novel, green, and sustainable method for synthesizing magnetic iron oxides from metallurgical copper slag (CS), leveraging its iron content as a valuable resource. Iron was extracted via acid leaching using edible citric acid (ECA), forming a citrate–iron complex (CSL), which was subsequently thermally decomposed at 300°C

The Effect of Electrolyte pH and Impurities on the Stability of Electrolytic Bicarbonate Conversion
ChemSusChem, Volume 18, Issue 6, March 15, 2025.The performance of bicarbonate electrolysis is largely controlled by the electrolyte inlet pH, the distance between the membrane and electrode, and the impurities present in the electrolyte. By complexing trace metal ions with ethylenediaminetetraacetic acid (EDTA), stability can significantly be improved and longer term operation can be achieved ...
