Figure 4. Electrophoretic mobility (EPM) data for (A) HS1 = 1 mg L-1, (B) HS2 = 1 mg L-1, (C) EPS1 = 1 mg L-1, and (D) EPS2 = 5 mg L-1. 
HS/EPS, 
AgCit = 2 mg L-1, AgCit = 2 mg L-1 + HS/EPS, 
AgPEG = 2 mg L-1, 
AgPEG = 2 mg L-1 + HS/EPS. HS = humic substances, EPS = extracellular polymeric substances, AgCit = silver nanoparticles capped with citrate, AgPEG = silver nanoparticles capped with polyethylene glycol.
