摘要
The effects of pulse ultrasound with different pulse parameters on the breakthrough curves of Geniposide on Resin 1300 were studied. The mass transfer model describing the adsorption process was constructed. Adsorption capability and the overall mass-transfer coefficient were obtained by fitting the constructed mass-transfer model and the experimental data. The effects of pulse ultrasound on adsorption of Geniposide on Resin1300 in a fixed bed were studied and compared. Amount of Geniposide adsorbed on Resin 1300 in the presence of ultrasound is lower than that in the absence of ultrasound, but the mass-transfer rate with ultrasonic irradiation is higher than that without ultrasound. Furthermore, mass transfer rate is enhanced by pulse modulation. In the conditions studied, the adsorption equilibrium constant decreases with increasing ultrasonic power, while the overall mass-transfer co-efficient increases. With increasing pulse duty ratio, adsorption equilibrium constant decreases initially, reaches a minimum when pulse duty ratio is 0.5, and then increases. On the contrary, the overall mass-transfer coefficient in-creases initially and reaches a maximum when pulse ratio is 0.5, and then decreases. Effects of pulse period on ad-sorption equilibrium and mass transfer rate reached the peak at pulse period of 28.6 ms.
有树脂 1300 上的 Geniposide 的突破曲线上的不同脉搏参数的脉搏超声的效果被学习。描述吸附过程的集体转移模型被构造。吸附能力和全面集体转移的系数被适合构造集体转移的模型和试验性的数据获得。在一张固定的床上的 Resin1300 上的 Geniposide 的吸附上的脉搏超声的效果被学习并且比较。在面对超声的树脂 1300 上吸附的 Geniposide 的数量当超声不在时是比那低的，但是没有超声，有超声的照耀的集体转移的率比那高。而且，集体转移率被脉搏调整提高。处于学习的条件，吸附平衡常数与增加超声的力量减少，当全面集体转移的系数增加时。与增加脉搏责任比率，吸附平衡常数开始减少，当脉搏责任比率是 0.5 时，到达最小，然后增加。相反，全面集体转移的系数开始增加并且当脉搏比率是 0.5，然后减少时，到达最大值。吸附平衡和集体转移率上的脉搏时期的效果在 28.6 ms 的脉搏时期到达了山峰。
