A　spherical　lignin　adsorbent　was　prepared　by　applying　the　reverse-phase　suspension　technique　with　raw　material　of　lignin　sulphate.　Then　the　study　regarding　the　adsorption　kinetics　and　thermodynamics　of　L-aspartic　acid　on　the　spherical　lignin　adsorbent　was　carried　out　through　static　experiments.　The　effect　factors,　i.e.,　solution　pH　and　temperature　etc.,　were　also　optimized.　The　results　indicated　that　the　equilibrium　adsorption　capacity　could　reach　518　mg/g　under　3.0　of　solution　pH.　And,　the　adsorption　rate　of　L-aspartic　acid　on　the　spherical　lignin　adsorbent　was　simultaneously　controlled　by　the　liquid　film　diffusion　and　the　intraparticle　diffusion.　The　adsorption　process　could　correspond　with　the　Langmuir　and　Freundlich　adsorption　isotherm,　Additionally,　the　enthalpy　(ΔH)　value　was　16.81　kJ/mol　indicating　adsorption　process　belonged　to　the　endothermic　chemical　adsorption　process.　And,　the　activation　energy　Ea=3.3406　kJ/mol　indicated　that　the　intraparticle　diffusion　was　predominant　during　the　adsorption　process.
