Ruthenium, (Ru) is a rare-earth metal, which is employed widely in metal-processing industries. This study recovered Ru from the ,wastewater, of an IC foundry by cementation using metallic aluminum (Al) powder as the sacrificial agent. Ru ions were efficiently reduced to the metal and coagulated with the derived aluminum hydroxide flocs.

However, the use of ,sulfuric acid, requires high safety measures. It is not only expensive to use, but also forms odorous hydrogen sulfide and mineral salts in ,wastewater, treatment. In contrast, carbon dioxide dissolves in water to form weakly acidic carbonic ,acid,, completely free from the problems posed by ,sulfuric acid,, and the ,neutralization, process is safe, harmless and efficient.

The process of adding carbon dioxide is called recarbonation and is often practiced in industrial ,wastewater neutralization,. The commonly used acids for pH adjustment of alkaline wastewaters are ,sulfuric acid, (H 2 SO 4 ), hydrochloric ,acid, (HCl), and nitric ,acid, (HNO 3 ). Among them, ,sulfuric acid, is the most widely used neutralizing agent.
