An experimental and thermodynamic equilibrium investigation of the Pb
Compared with Fig. 8, Cr and Mn do not respond to the addition of chlorine, whereas Cu, Zn, Ni and Pb are affected by the chlorides at different levels. Pb displays the greatest response to the addition of chlorine: at 400 K, Pb reacts with Cl and gaseous substances form, such as volatile PbCl 4 (g), PbCl 2 (g) and PbCl(g).

Suppressing Heavy Metal Leaching through Ball Milling of …
Ball milling is investigated as a method of reducing the leaching concentration (often termed stablilization) of heavy metals in municipal solid waste incineration (MSWI) fly ash. Three heavy metals (Cu, Cr, Pb) loose much of their solubility in leachate by treating fly ash in a planetary ball mill, in which collisions between balls and fly ash drive various …
