摘要
通过比较树脂的脱色效果、脱色条件、树脂再生方法对多种树脂进行了筛选实验。结果显示,D201吸附树脂脱色性能良好,再生使用次数多,回收率稳定,适合维生素C交换液的脱色,确定了最佳实验条件。与传统工艺相比,树脂脱色工艺具有生产简单、环境污染小等优点。
The selection of type of macroporous adsorptive resin, the condition of decolourization and its recovery were investigated systematically. The result indicates that 3＇ is the best resin in all the resins and the optimal experiment conditions was established. Compared with traditional technique, resin decolourization has advantage of simple procedure and no environmental pollution.
