Abstract：

A　novel　spherical　chelation　adsorbent　was　prepared　from　the　waste　of　acrylic　fiber,　and　the　adsorption　kinetic　of　Cr(VI)　on　the　adsorbent　was　investigated.　The　results　suggested　that,　within　the　observed　temperature　and　concentration　range,　the　adsorption　rate　of　Cr(VI)　was　high　and　the　equilibrium　was　reached　in　nearly　30min.　The　experimental　data　for　the　adsorption　systems　followed　a　second-order　equation,　and　the　chemical　adsorption　is　the　main　adsorption　process　with　low　energy　and　the　activation　energy　Ea　is　36.03kJ/mol,　the　adsorption　involves　diffusion　controlled　process　combined　by　surface　diffusion　and　intra-particle　diffusion.　©　2011　IEEE.
