In　this　work,　a　sulfonated　polystyrene　sphere　(SPS)　based　magnesium　silicate　nanocomposite　(SPS@MgSix)　with　superior　adsorption　capability　has　been　prepared　for　the　removal　of　BPA,　a　kind　of　emerging　pollution　existed　in　various　wastewaters.　It　was　obtained　by　in　situ　growth　of　the　Talc-phase　Mg3Si4O9(OH)(10)　(MgSi)　on　the　surface　of　SPS,　in　which　the　SPS　substrate　can　effectively　avoid　the　agglomeration　of　MgSi.　Scanning　electron　microscope　(SEM)　has　shown　that　interwoven　nano-sized　MgSi　uniformly　distributes　on　the　surface　of　SPS,　leading　to　a　high　adsorption　capacity　(Q(0):　357.14　mg　L-1)　for　removing　bisphenol　A　(BPA).　It　is　worth　noting　that　these　composite　materials　also　exhibit　relative　good　adsorption　capability　even　under　high-concentration　salt　conditions,　for　example,　the　adsorption　capacity　still　keeps　at　about　331.14　mg　g(-1)　in　the　presence　of　high　concentration　Na+　or　Ca2+.　The　Zeta　potential　tests　indicate　that　the　high　adsorption　capacity　may　be　related　to　an　electrostatic　interaction　between　SPS@MgSix　and　BPA.　The　excellent　adsorption　behaviors　of　SPS@MgSix　show　that　it　is　a　highly　promising　candidate　for　removing　BPA　in　aqueous　solution.
