Lignin-polypyrrole　nanocomposite　particles　(EHL-PPY)　were　prepared　via　an　in-situ　polymerization　of　pyrrole　monomers　in　the　existence　of　enzyme　hydrolysis　lignin.　Adsorption　property　of　silver　ions　onto　EHL-PPY　nanocomposite　particles　w　as　investigated　through　a　batch　adsorption　technique.　Effects　of　adsorbent　concentration,　adsorption　time　and　initial　silver　ion　concentration　on　the　adsorption　were　examined.　The　results　show　that　the　maximal　adsorption　capacity　of　silver　ions　onto　the　EHL-PPY　nanocomposite　particles　reaches　882.0　mg/g　at　35.　After　adsorption,　the　product　of　nanocomposite　particles　was　characterized　by　TEM　and　XRD.　It　is　found　that　the　silver　ions　are　reduced　to　silver　nanoparticles　wit　h　the　mean　diameters　of　22~56　nm　after　adoption.　This　result　indicates　that　EH　L-PPY　nanocomposite　particles　possess　reactive　adsorbability　of　silver　ions.　Therefore,　the　EHL-PPY　nanocomposite　particles　can　be　effectively　used　as　an　adsorbent　for　removal　and　recovery　of　silver　ions　from　waste　water.　©,　2015,　Chengdu　University　of　Science　and　Technology.　All　right　reserved.
