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。

摘  要:
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.
