In the new method, 1.0 mol l-1 solution of sodium chloride (MOC–SC) and other salts were used for extraction of the active coagulation component. Batch coagulation experiments were conducted using 500 ml of low turbid water (50 NTU). Coagulation efficiencies were evaluated based on the dosage required to remove kaolinite turbidity in water.

Extraction methods Extraction is the separation of medicinally active portions of plant using selective solvents through standard procedures [11]. The purpose of all extraction is to separate the soluble plant metabolites, leaving behind the insoluble cellular marc (residue).The initial crude
