大孔吸附树脂对莽草酸粗提液的脱色研究
Research on Decolorazation of Shikimic Acid Extract with Macroporous Resin
摘要
Abstract
In this paper, nine kinds of macroporous resin were screened to study the decolonization rate and the recovery rate of shikimic acid. Through the static and dynamic adsorption experiments for the selected resin, the optimum conditions of decolorization of shikimic acid extract and resin regeneration were obtained. The results showed that the HPD-100 resin was the best. The best technology conditions were: temperature 25℃ , pH value 4.0, total solids content 0. 5% , flow rate 4BV/h. Under these conditions, the decolorization ratio was about 70% at 25BV, the recovery ratio of the shikimic acid was 91.2% . The regeneration was better by using 70% ethanol solution as the regenerates and flow rate at 2BV/h.关键词
