A　large　amount　of　organophosphorus-containing　wastewater　is　produced　in　spent　lithium-ion　battery　disposal.　Forward　osmosis　(FO)　offers　unique　advantages　in　purifying　this　kind　of　wastewater　if　suitable　draw　solutes　-　the　core　of　FO　technology,　are　available.　Herein　we　synthesize　several　pH-sensitive　zinc　complexes,　namely　ZnATMP-iNa　(i　=　0,　1,　2,　3,　4),　from　ZnSO4　and　amino　tris(methylene　phosphonic　acid)　(ATMP)　obtained　from　scale　inhibitor　wastes　for　organophosphorus-containing　wastewater　remediation.　Among　these　ZnATMP-iNa,　ZnATMP-3Na　best　meets　the　standards　of　an　ideal　draw　solute.　This　makes　ZnATMP-3Na　outperform　other　reported　draw　solutes.　0.6　M　ZnATMP-3Na　produces　a　water　flux　of　12.7　LMH,　136　%　higher　than　that　of　NaCl　and　a　solute　loss　of　0.015　g/L,　lower　than　that　of　NH4HCO3　(0.83　g/L).　In　organophosphorus-containing　wastewater　treatment,　ZnATMP-3Na　has　higher　water　recovery　efficiency　(8.3　LMH)　and　sustainability　than　NaCl　and　NH4HCO3,　and　is　sufficient　to　handle　large　quantities　of　wastewater.　Remarkably,　the　pH-responsive　property　allows　ZnATMP-3Na　to　be　readily　recovered　through　pH-control　and　reused　in　FO.　The　ionic　property,　expanded　cage-like　structure　and　easy-recycling　make　ZnATMP-3Na　achieve　sustainable　FO　separation　and　superior　to　other　draw　solutes.　This　study　provides　inspiration　for　draw　solute　design　from　wastes　and　extends　FO　application　to　organophosphorus-containing　wastewater　remediation.
