Abstract:The stable existence of heavy metals in soil under natural conditions is the core issue in heavy metal pollution solidification and remediation technology. This paper takes the common heavy metal ion Cd2+ as an example to analyze the stability of the combination of heavy metal ions and common ion groups in soil. The stability and existing form of Cd are analyzed by using the first principle, and the free energy, band structure, and partical density of states (PDOS) of CdCO3, CdSO4, CdCl2, CdSiO3 are calculated… Show more
