Using　ion　exchange　resins　to　recover　acetic　acid,　the　adsorption　process　was　studied　systematically.　Through　the　resin　selection　experiments,　D311　resin　showed　a　better　capacity　and　smaller　constriction.　The　adsorption　and　desorption　process　of　dilute　acetic　acid　were　studied　with　the　selected　D311　resin,　and　the　optimized　operation　conditions　were　obtained.　When　the　temperature　was　30.0°C　and　the　feed　velocity　4.0　mL/min,　the　adsorption　rate　reached　93.97%.　When　the　temperature　was　50.0°C,　and　the　concentration　of　NaOH　3.98　mol/L,　velocity　1.0　mL/min,　the　desorption　rate　reached　100%.　Moreover,　the　resin　regenerative　experiments　indicated　that　D311　resin　regeneration　had　good　repetition　and　excellent　mechanical　strength.
