摘要

Extraction and separation of Radish red pigment from a waste water of salting Radish was studied on D61 resin.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 pigment adsorbed on D61 resin 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·hm^-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 could′t be adsorbed on the resin.Finally, a paste product with yield of 1.96mg·100ml^-1 waste water was obtained after alcohol evaporation and vacuum drying.
