摘要:

采用XDA-3、XDA-6 和XDA-7 大孔树脂对甘蔗清汁进行脱色。通过单因素试验,考察了温度、时间、树脂用量对树脂脱色性能的影响,筛选出XDA-6 树脂进行静态吸附动力学和吸附等温线研究。结果表明,XDA-6吸附动力学符合液膜扩散方程,扩散速率常数为0.0301min-1,吸附等温线符合Freundlich 方程。

关键词: 大孔吸附树脂, 脱色, 蔗汁, 脱色率

Abstract:

Three types of macroporous resins XDA-3, XDA-6 and XDA-7 were used for the decolorization of sugar juice concentrate. According to investigations of the effects of resin amount, adsorption temperature and adsorption time on decolorization efficiency, XDA-6 was selected for further investigations. The adsorption kinetics of XDA-6 was consistent with the equation of liquid membrane diffusion with 0.0301/min diffusion rate constant. Moreover, the adsorption isotherm also complied with the Freundlich equation.

Key words: macroporous resin, decolorization, sucrose juice concentrate, decolorization efficiency
