چکیده

The natural coagulant Moringa oleifera (MO) is considered to be an efficient coagulant with some advantages over chemical coagulants. Fluoride removal, using MO seed extract was investigated. The influence of MO dosage, initial F concentration, and pH were determined and modeled using the Box-Behnken design response surface methodology. With a constant initial F concentration, it was found that increasing the MO dose resulted in increased F removal. pH had no meaningful effect on F removal. Statistical and graphical tools confirmed the adequacy of the predicted model. Based on an optimized condition, for 85.4% removal of 8 mg/L of fluoride, a coagulant dosage of 900 mg/L is needed.

Isolation and characterization of coagulant extracted from Moringa oleifera seed by salt solution.

It is known that M. oleifera contains a natural coagulant in the seeds. In our previous research, the method using salt water to extract the active coagulation component from M. oleifera seeds was developed and compared with the conventional method using water. In this research, the active coagulation component was purified from a NaCl solution crude extract of Moringa oleifera seeds. The activ...
