Electroconductive　poly(N-butylaniline)lignosulfonate　(PBALS)　composite　nanospheres　were　prepared　in　a　facile　way　by　in　situ,　unstirred　polymerization　of　N-butylaniline　with　lignosulfonate　(LS)　as　a　dispersant　and　dopant.　The　LS　content　was　used　to　optimize　the　size,　structure,　electroconductivity,　solubility,　and　silver　ion　adsorptive　capacity　of　the　PBALS　nanospheres.　Uniform　PBALS10　nanospheres　with　a　minimal　mean　diameter　of　375　nm　and　high　stability　were　obtained　when　the　LS　content　was　10　wt?%.　The　PBALS10　nanospheres　possess　an　increased　electroconductivity　of　0.109　S?cm-1　compared　with　that　of　poly(N-butylaniline)　(0.0751　S?cm-1).　Furthermore,　the　PBALS10　nanospheres　have　a　maximal　silver-ion　sorption　capacity　of　815.0　mg?g-1　at　an　initial　silver　ion　concentration　of　50　mmol?L-1　(25?degrees　C　for　48　h),　an　enhancement　of　70.4?%　compared　with　PBA.　Moreover,　a　sorption　mechanism　of　silver　ions　on　the　PBALS10　nanospheres　is　proposed.　TEM　and　wide-angle　X-ray　diffraction　results　showed　that　silver　nanoparticles　with　a　diameter　size　range　of　6.855　nm　was　achieved　after　sorption,　indicating　that　the　PBALS10　nanospheres　had　high　reductibility　for　silver　ions.
