14/9/2000, · The TCLP leaching solution is a solution ,containing, acetic acid that is adjusted to a pH of 4.93 or 2.88, depending on the acidity of the waste sample. EPA developed the SPLP as a method to predict leaching from wastes or soils under exposure to the slightly ,acidic,, dilute solution generated by normal rainfall.

Powder, chalcopyrite in the new ,powder, electrode system was held at 0.45 V in the presence ,of copper, ion and sulfuric acid media followed by an application of potential in the anodic direction. Besides the chalcopyrite oxidation peak, a small peak resulted at ~0.55 V; this peak corresponds to reduced chalcocite, because it occurs at the same potential as the chalcocite oxidation peak..
