A novel method for extraction of a proteinous coagulant from Plantago ovata seeds for water treatment purposes
Several chemicals have been applied in the process of coagulant extraction from herbal seeds, and the best extraction has been obtained in the presence of KCl or NaNO3 [1–3], and NaCl [4]. However, the main challenge posed to these methods of coagulant extraction is their relatively low efficiency f...

• Two consecutive elutriations of crude extract was directly performed using 0.025-M FeCl3 and 0.05-M FeCl3 according to the basis of the ion-exchange processes. |
