This research aims to address this issue by optimising an electrocoagulation-adsorption (EC-AD) process using two aluminium electrodes and activated carbon. The applied voltage (5, 15, and 20V) and adsorbent dosage (0.20, 0.50, and 1.00g) parameters were varied to treat a synthetic ,wastewater, solution ,containing, 100 mg/L of fluorine.

Rechargeable alkaline batteries ,containing zinc, anodes suffer from redistribution of active material due to the high solubility of ZnO in the electrolyte, limiting achievable capacity and lifetime. Here, we investigate pre-saturating the KOH electrolyte with ZnO as a strategy to mitigate this issue, utilizing rechargeable Ni–Zn cells.

However, the practicality of using pH to control the, neutralization, reaction is greatly influenced by the buffer capacity of the water. For example, it is much easier to, neutralize, an, acidic waste containing hydrochloric acid, to a pH of 7.5 with sodium carbonate than with caustic soda. This is illustrated by Figure 13.1. Treating an, acidic wastewater, may be relatively easy because the allowable
