A　spherical　lignin-based　ion　exchange　resin　was　prepared　with　calciumlignosulfonate　as　raw　material　in　a　cheap　and　non-toxic　disperse　phase　by　reversed　phase　suspension　polymerization　technique.　The　effect　of　disperse　phase,　dispersing　agent　and　cross-linking　agent　dosage,　polymerization　temperature　and　mixing　speed　on　the　suspension　polymerization　and　sphericization　were　studied.　The　fundamental　performances　of　the　resin　including　appearance,　particle　size,　moisture　content,　density,　and　exchange　capacity　were　characterized.　At　the　optimal　conditions,　the　ion　exchange　capacity　of　3.83　mmol/L　was　reached.
