Temperature responsive flocculation and solid-liquid separations with charged random copolymers of poly(N-isopropyl acrylamide)

► Comprehensive investigation of selective temperature responsive flocculation with charged random co-polymers of PNIAPM covering both sedimentation and secondary consolidation. ► Temperature influences settling and consolidation less with charged co-polymers which also act as conventional flocculants compared to neutral PNIPAM. ► Secondary consolidation is reduced with random charged co-polymers of PNIPAM compared to neutral PNIPAM even after the temperature is reduced to below the LCST.
