Synthesis of poly(hexachlorocyclotriphosphazene-co-phenolphthalein) microspheres with negative charges for the selective removal of cationic dyes

Abstract

Through the precipitation polymerization method, polyphosphazene microspheres (PHCPP) were prepared using hexachlorocyclotriphosphazene (HCCP) and phenolphthalein (PP) as precursors. Subsequently, PHCPP microspheres, which are enriched with abundant hydroxyl functional groups and...
