The exchange capacity of adsorption the pigment was equal to 60. 91mg· g￣(-1) wet resin, and the equilibium time only 40mins. All Radish red pigmeent adsorbed on D61 basin was eluted using a eluent in which concentraction of HCl or alcohol was 0. 1mol· L￣(-1) or 80% at 50℃ when the flow rate was at 2BV· hr￣(-1). Stability Of D61 resin was very well ,and while the resin was recycled fifteen times, the exchange capacity was only decreased 11. 9% , and the exchange capacity didn' t changed. Because of negative ion of mustard oil, it couldn' t be adsorbed on the resin. Finally, a paste plxiduct with yield of 1. 96mg· 100ml￣(-1) waste water was obtained after alcohol evaporation and vacuum drying.
