| his thesis examines the retention of three heavy metals (Pb, Cu, Zn) on a predominantly illite clay soil initially saturated with calcium and magnesium. The heavy metal retention mechanisms were examined both experimentally, using batch equilibrium and precipitation tests, and analytically, using the geochemical equilibrium speciation model MINTEQA2. Heavy metal retention was examined in both non-competitive (single metal) situations and competitive (multi-metal) situations. A definite adsorption selectivity order of Pb... |
