Coprecipitation-adsorption plays a significant role during coagulation-flocculation-sedimentation (C/F/S) of antimony (Sb) in water. This work uses Box–Behnken statistical experiment design (BBD) and response surface methodology (RSM) to investigate the effects major operating variables such as initial Sb(III, V) concentration (100–1000 µg/L), ferric chloride (FC) dose (5–50 mg/L), pH (4–10) on...

three series of a polydispersed system of sulfadiazine and sulfamerazine mixture were prepared, and effect of three inorganic electrolytes on flocculation of this system was studied. we have found the appropriate flocculating agent and also its necessary concentration. results obtained have shown that there is a relation between flocculation and sedimentation volume, but the hard cake formed wh...
