摘　　要：本文研究了用Ｄ６１树脂吸附和分离萝卜红色素的方法。试验结果表明：Ｄ６１树脂吸附和分离萝卜红色素的交换容量为６０．９１ｍｇ／ｍｌ湿树脂，吸附平衡时间为４０分钟。被吸附的萝卜红色素用含０．１ｍｏｌＨＣｌ／ｌ的８０％乙醇洗脱，洗脱液温度为５０℃，流速为２ＢＶ／ｈｒ。Ｄ６１树脂非常稳定，使用１５次后交换容量仅降低１１％，再生１２次对其吸附能力无明显影响。萝卜苷是一种负离子，因而不被Ｄ６１树脂吸附。经过回收乙醇和真空干燥得到膏状的萝卜红色素产品，收率为１．９６ｍｇ／１００ｍｌ废水。A method of adsorbing and separating Radish red pigment with D61 resin was studied.Adsorption capacity of D61 resin for the pigment was 60. 91mg. ml-1 wet resin, and the equilibrium time was 40mins. All Radish red pigment that had been absorbed by D61 resin was eluted at 50℃ by a eluent in which concentraction of HCl and alcohol was 0. 1mol. l-1 and 80% respectively at the flow rate of 2BV/hr. After fifteen times of use, the exchange capacity was decreased by 11. 9%. After the resin was reactivated twelve times, the capacity didn't changed. Because mustard oil is negative ion, it was not adsorbed by the resin. After distilation and vacuum drying, a paste product was obtained with yield of 1.96mg. 100ml-1 waste water.
