A　high　specific　surface　area　amine-modified　polymer　of　intrinsic　microporosity　(NH2-PIM-1)　was　synthesized　by　reducing　nitriles　to　amines　in　the　polymer　of　intrinsic　microporosity　(PIM-1)　as　an　adsorbent　to　remove　sunset　yellow　FCF　(SY)　from　aqueous　solution.　The　physicochemical　properties　of　NH2-PIM-1　were　characterized　by　infrared　spectra　(IR),　scanning　electron　microscope　(SEM),　thermogravimetric　analysis　(TGA),　nuclear　magnetic　resonance　(NMR)　and　N-2　adsorption-desorption　isotherms　measurement.　The　effect　of　initial　solution　pH　value,　dosage　of　adsorbent,　contact　time　and　initial　SY　concentration　were　systematically　investigated.　The　sunset　yellow　FCF　adsorption　equilibrium　was　attained　after　10　min　and　the　adsorption　capacity　could　reach　348.16　mg/g,　which　was　superior　to　most　of　the　other　adsorbents　previously　reported.　Kinetics　and　isothermal　model　experiments　indicated　that　the　adsorption　of　sunset　yellow　matched　the　pseudo-second-order　kinetic　model　and　Langmuir　model,　respectively.　Thermodynamic　analysis　showed　that　the　adsorption　was　endothermic,　spontaneous　and　physical　adsorption　process.　These　results　suggested　that　the　NH2-PIM-1　was　a　rapid　and　efficient　kind　of　adsorbent　for　removal　of　sunset　yellow　FCF.
