“…Generally, the acid dissolution and neutralization reactions are very fast, but the oxidation-reduction reaction is slow. If there was only acid dissolution or neutralization reaction in the dissolution process, it would not need too much time to get the maximum dissolution ratio [19].…”

“…Hydrometallurgy has some benefits such as low cost requirements, possible recovery of leachants, and decrease of air pollution as there are no particles produced [11]. The experimental results indicated that in the case of Zn, the efficiency of the hydrometallurgical method is between 73% and 100% [12][13][14].…”

The structural, optical and photocatalytic properties of two zinc oxides prepared from spent alkaline batteries were analysed. After leaching the anode of alkaline batteries, zinc was precipitated from the leachate liquor by introducing oxalic acid (O-ZnO) or sodium carbonate (C-ZnO). The structure of ZnO samples were analysed by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), SBET, DRS-UV-Vis spectroscopy and positron annihilation lifetime spectroscopy (PALS). Both oxides present the ZnO wurzite structure and similar morphology. C-ZnO presents a cell lower lattice parameters and bang gap energy (2.99 eV) than O-ZnO (3.05 eV), possibly due to higher concentration of oxygen vacancies. The photocatalytic activity in the degradation of methylene blue (MB) of O-ZnO (achieving 70% MB degradation at 90 min) was superior to C-ZnO, due to its higher surface area and degree of crystallinity and lower bulk/surface defects ratio.

“…This presents a major environmental and health threat [2]. Waste batteries are causing serious concern owing to their toxicity, abundance, and permanence in the environment [3]. Therefore, reutilization and recycling of materials in order to minimize this waste are being considered.…”
