A　novel　adsorbent　NH2/MCM-41/NTAA,　capable　of　simultaneous　adsorption　of　cations　and　anions　from　aqueous　solution,　was　prepared　by　immobilization　of　amine　and　nitrilotriacetic　acid　anhydride　(NTAA)　onto　MCM-41.　The　structures　and　properties　before　and　after　surface　modification　were　systematically　investigated　through　X-ray　diffraction　(XRD),　transmission　electron　microscope　(TEM)　and　scanning　electron　microscope　(SEM),　nitrogen　adsorption-desorption,　and　infrared　spectroscopy　(FTIR),　thermogravimetry　(TGA)　and　X-ray　photoelectron　spectroscopy　(XPS).　They　together　confirm　that　the　amine　and　NTAA　group　were　chemically　bonded　to　the　internal　surface　of　the　mesoporous.　The　NH2/MCM-41/NTAA　were　used　to　adsorb　Pb2+　and　MnO4-　in　an　aqueous　solution　in　a　batch　system,　and　the　maximum　adsorption　efficiency　was　found　to　occur　at　pH　5.0　and　3.0,　respectively.　NH2/MCM-41/NTAA　exhibit　preferable　removal　of　Pb2+　through　electrostatic　interactions　and　chelation,　whereas　it　captures　MnO4-　by　means　of　electrostatic　interactions.　The　experimental　data　are　fitted　the　Langmuir　isotherm　model　reasonably　well,　with　the　maximum　adsorption　capacity　of　147　mg/g　for　Pb2+　and　of　156　mg/g　for　MnO4-.　The　adsorption　rates　of　both　Pb2+　and　MnO4-　are　found　to　follow　the　pseudo-second　order　kinetics.　Furthermore,　the　NH2/MCM-41/NTAA　adsorbent　performs　good　recyclability　and　reusability　for　5　cycles　use.　This　study　indicates　a　potential　applicability　of　NH2/MCM-41/NTAA　as　new　absorbents　for　effective　simultaneous　adsorption　of　hazardous　metal　ions　and　anions　from　wastewater.　©　2015　Elsevier　B.V.　All　rights　reserved.
