Self-assembled　poly(N-methylaniline)　(PNMA)　microspheres　were　prepared　in　a　facile　way　by　an　unstirred　polymerization　of　N-methylaniline　monomers　with　ammonium　persulfate　as　an　oxidizing　agent　at　different　temperatures.　The　polymers　were　characterized　by　FTIR　and　UV-vis　spectroscopy,　SEM,　TEM　and　wide-angle　X-ray　diffraction.　Furthermore,　adsorption　property　of　PNMA　microspheres　for　silver　ions　from　aqueous　solution　was　investigated　by　batch　experiments.　The　results　revealed　that　PNMA　showed　a　high-performance　adsorption　for　silver　ions　by　chelation　and　redox　reaction.　The　maximum　adsorption　capacity　was　up　to　2.460g/g　for　silver　ions　on　PNMA　microspheres　prepared　at　0　degrees　C,　at　an　initial　silver　ion　concentration　of　160mmol/L　at　25　degrees　C　for　48hr.　The　adsorption　process　fits　the　pseudo-second-order　kinetics　and　Freundlich　isotherm　models.　Moreover,　the　PNMA　microspheres　exbihit　high　reductive　performances　for　Au(III)　and　Pd(II)　ions.　Therefore,　the　PNMA　microspheres　have　great　potential　application　in　removal　and　recovery　of　metal　ions　from　industrial　wastewater.
