Removal of nickel ions from aqueous solution by low energy-consuming sorption process involving thermosensitive copolymers with phosphonic acid groups

► Synthesis of low LCST statistical copolymer (thermosensitive/complexing). ► Investigation of sorption efficiency for (Ni2+ ions) in various operating conditions. ► High sorption efficiency comparing to similar thermosensitive polymer with sorption properties. ► Link between the copolymer architecture and the sorption capacity.
