The synthesized graft copolymers were characterized by intrinsic viscosity measurements, Fourier transform infrared spectroscopy, elemental analysis （C, H, N, O and S） and scanning electron microscopy. Ag-g-P （HEMA）-2 showed a much higher flocculation efficacy than agar. The optimized dosage of flocculation for Ag-g-P （HEMA）-2 in the wastewater was found to be 0.75 ppm. Compared to agar, Ag-g-P（HEMA）-2 was found to considerably reduce the pollutant load in the wastewater.展开更多
