| Popis: | Combined contaminants of antibiotics and heavy metals in wastewater have caused global concern. Reusable flocculant CS-g-PNNPAM with different lengths of grafted thermo-responsive branches were synthesized for the removal of different types of combined contaminants (tetracycline-Cu(II), tetracycline-Zn(II), sulfadiazine-Cu(II), and sulfadiazine-Zn(II)) from wastewater. Response surface methodology was employed to study interactive effects among wastewater temperature (X1), flocculant stock solution temperature (X2) and flocculant dosage (X3). The flocculation difficulty for different types of combined contaminants went with the sequence of sulfadiazine-Cu(II) |
