The　sustainable　development　of　tungsten　and　molybdenum　resources　requires　a　new　clean　and　recyclable　separation　technology.　This　work　proposes　a　recyclable　clean　separation　technology　of　tungsten　and　molybdenum　with　a　porous　amine　resin.　The　resin　was　well　prepared　by　assembling　amine　groups　on　trioctylamine　(TOA)　and　the　porous　resin　matrix　D301　by　the　dipping　method.　Here,　pH　7.8,　temperature　25　&　DEG;C,　and　reaction　time　240　min　was　used　as　optimum　condition,　resulting　in　the　highest　sorption　capacity　236　mg　g(-1),　and　it　has　a　good　cycle　performance,　exhibiting　a　retention　rate　of　90%　after　five　cycles.　Experimental　spectroscopy　combined　theoretical　calculation　confirmed　that　this　sustainable　sorption　behavior　is　substantially　related　to　the　amine　functional　groups　on　the　resin.　Experimental　spectroscopy　illustrated　that　the　Cl-　ions　in　the　amine　resin　and　the　MoS(4)(2-&　nbsp;)ions　were　subjected　to　ion　exchange.　Theoretical　investigations　further　confirm　that　the　sorption　site　is　at　the　N　atoms,　the　sorption　behavior　is　chemical　binding　with　the　binding　energy　-0.055　Ha,　and　the　bonding　method　is　the　s　orbit　of　the　N　atoms　in　the　amine　resin　hybridized　with　the　s　orbit　of　the　S　atoms　in　the　amine　resin.　Owing　to　such　an　excellent　performance　in　the　selective　sorption　of　molybdenum　from　the　tungstate　solution,　the　amine　resin　is　greatly　promising　in　the　tungsten　and　molybdenum　waste　recovery　field.
