    Sep 01 2015 · The results indicate that the volatility of the target metals was enhanced as the chlorine concentration increased. Inorganic-Cl influenced the volatilization of heavy metals in the order of Pb > Zn > Cr > Cu > Mn > Ni. However the effects of organic-Cl on the volatility of Mn Pb and Cu were greater than the effects on Zn Cr and Ni.
