Impure sugar soln. was contacted with 0.01-1.5μ diameter ion exchange particles having 0.7-1.5 ion exchanging functional groups per monomer unit to purify impure sugar soln.(decolorization and clarifying), and then ion exchange particles were separated from sugar soln. The ion exchange resin was made from styrene-divinylbenzene copolymer.
