The　reversible　removal　of　concurrent　perfluorinated　compounds　and　heavy　metal　ions　is　highly　desirable　but　challenge　in　water　remediation.　Herein,　we　present　a　tetraethylenepentamine-modified　covalent　organic　polymer　(COP-NH2)　containing　flexible　multi-amines　and　hydrophobic　triptycene　through　post-synthetic　amidation　reaction　of　carboxyl-containing　covalent　organic　polymer.　The　sorption　behaviors　of　COP-NH2　toward　perfluorooctane　sulfonate　(PFOS)　and　dichromate　were　investigated　in　terms　of　the　adsorption　kinetics,　isotherms,　simultaneous　removal　capability　and　reusability.　The　maximum　uptake　capacities　of　PFOS　and　dichromate　on　COP-NH2　are　1.40　mmol　g−1　and　304.9　mg　g−1,　respectively,　while　their　initial　adsorption　rates　are　as　high　as　6.45　mmol　g-1h−1　and　164.2　mg　g−1　min−1,　respectively.　Both　of　them　surpass　majority　of　the　sorbents　of　the　environmental　contaminants.　Importantly,　PFOS　and　dichromate　in　the　stimulated　electroplating　wastewater　could　be　simultaneously　and　reversibly　removed　in　high　uptake　efficiency　over　99%.　The　promising　performance　is　mainly　attributed　to　protonation　of　the　amines　in　COP-NH2,　the　resultant　electrostatic　interactions　have　been　confirmed　to　play　dominant　roles　in　both　PFOS　and　dichromate　adsorption.　This　work　provides　multifunctional　sorbents　for　reversible　removal　of　concurrent　contaminants　from　wastewater.　©　2022　Elsevier　B.V.
