原始语种摘要: The acid mine drainage (AMD) was poured into five 500 ml glass beakers. The samples were dosed with synthetic af-PFCl of Ca(OH)2 and af-PFCl of CaCO3 polymers respectively. The samples were treated in a jar test and a shaker at 250 rpm for 2 min, and thereafter were allowed to settle for an hour after which the pH, conductivity and turbidity (TSS) were measured. A similar second set of experiments was conducted by placing the samples in a shaker at 250 rpm for 2 min, after which three measurements were conducted after 1, 2 and 6 h. Similar third and fourth set of experiments was conducted dosing the AMD with 0.043 M of Ca2+ in Ca(OH)2, and 0.043 M Ca2+ in CaCO3 respectively. A fifth set of experiment was conducted by dosing the AMD sample with 0.021 and 0.043 M Ca2+ in Ca(OH)2...
