Heavy metal [Cd(II), Cr(VI), Pb(II)] removal efficiencies of PSAC, Mg/Si-PSAC, and Ag-PSAC in the presence of (a) single heavy metal, (b) multi-heavy metal, and (c) multi-heavy metal with microorganisms (Escherichia coli), and (d) heavy metal removal efficiencies of different carbon media combinations in the presence of multi-heavy metal and microorganisms (Combination 1—PSAC + Mg/Si-PSAC, 2—PSAC + Ag-PSAC, 3—Mg/Si-PSAC + Ag-PSAC, 4—PSAC + Mg/Si-PSAC + Ag-PSAC) (initial heavy metal concentration: each 1 mg L−1, initial E-coli population: 1.0 × 104 CFU 100 mL−1, dosage: 0.1 g, solution volume: 200 mL, reaction time: 60 min, RT).
