This study reports a facile technique to synthesize and tune the cationic polymer, poly(3-acrylamidopropyl)trimethylammonium chloride (PAPTAC), in terms of molecular weight surface change for harvesting three microalgae species (Scenedesmus sp., P.purpureum, C. vulgaris). The PAPTAC polymer was synthesised by UV-induced free-radical polymerisation. Polymer tuning demonstrated regulating monomer concentration (60 360 mg/mL) UV power (36 60 W) obtained evaluated different compared commercially available polymer. highest flocculation efficiency Scenedesmus sp.
