Research on Flocculation Behavior in Diethyl Phthalate Removal from Water by Using Anionic Flocculants P(AM-AA-AMPS)

Abstract:

Flocculation process with P(AM-AA-AMPS) as flocculants was used for the DEP removal from water. The structure and morphologies of the flocculants was characterized by scanning electron microscope (SEM). To maximize the DEP removal efficiency, single factor technique and an orthogonal array L₉ (3⁴) were employed to optimize the factors of dosage, initial pH value and stirring time. The results show that the optimal conditions are dosage of 10mg·L^-1, initial pH value of 9 and stirring time of 6min. Moreover, flocculants dosage is the best significant factors in DEP removal.
