摘要:

以改性松香为交联骨架,季铵盐阳离子为官能团,制备松香基阴离子交换树脂(RAER),研究其对蔗汁中代表性色素类黑精的吸附性能。采用静态吸附法对树脂投加量、吸附温度、pH值以及吸附时间4个单因素进行探索,在类黑精溶液初始质量浓度350 mg/L时,得到最佳吸附条件为:RAER投加量0.06 g/mL,温度333 K,pH值7.0,时间2 h。在最佳吸附条件下,RAER对类黑精的最大吸附量1.29 mg/g,吸附率达到22.07%,表明松香基阴离子交换树脂对类黑精有较好的吸附效果。

Abstract:

Rosin-based anionic exchange resin(RAER) was prepared by using modified rosin as the cross-linking skeleton, and quaternary ammonium cations as the functional group. And then, its adsorption performance on melanoidin which was arepresentative pigment in sugar juice was investigated. The four single factors(resin dosage, adsorption temperature, pH value and adsorption time) were optimized by the static adsorption experiments. When the initial mass concentration of melanoidin was 350 mg/L, the optimum adsorption conditions were resin dosage 0.06 g/mL, temperature 333 K, adsorption time 120 min and pH value 4.92. At the optimal adsorption conditions, the maximum adsorption capacity of melanoidins was 1.29 mg/g and the adsorption rate was 22.07%, which indicated that the rosin-based anionic exchange resin had superior adsorption performance on melanoidins.

Key words: rosin, anionic exchange resin, melanoidin, adsorption
