A　new　nanocomposite,　lignosulfonate-graphene　oxide-polyaniline　(LS-GO-PANI),　was　prepared　from　aniline　via　an　in　situ　polymerization　in　the　presence　of　lignosulfonate　and　graphene　oxide.　The　morphology　and　structure　of　the　LS-GO-PANI　ternary　nanocomposite　were　characterized　by　FE-SEM,　TEM,　FTIR,　and　UV-vis　spectroscopy.　Furthermore,　the　adsorption　property　of　Pb(II)　ions　onto　the　nanocomposite　was　studied.　The　effects　of　adsorption　time,　initial　pH　value,　adsorbent　concentration,　and　initial　adsorbate　concentration　on　the　adsorption　of　Pb(II)　ions　in　aqueous　solution　were　investigated　by　batch　experiments.　The　LS-GO-PANI　ternary　nanocomposite　showed　an　adsorption　capacity　as　high　as　216.4　mg　g-1　for　Pb(II)　ions　at　30　°C.　Moreover,　the　adsorption　kinetic　and　equilibrium　data　were　described　well　with　the　pseudo-second-order　and　Langmuir　isotherm　models　for　the　Pb(II)　ions　adsorption　process.　The　results　showed　that　the　LS-GO-PANI　ternary　nanocomposite　has　great　potential　application　in　removal　of　Pb(II)　ions　from　industrial　wastewater.　©　2014　American　Chemical　Society.
