Study on Purification of Chestnut Shell Tannin
摘要
Abstract
Purification of chestnut shell tannin from generally abandoned chestnut shell was studied. The effect of adsorbent, pre-column concentration, eluent, pH value of distilled water and flow rate on tannin yield was tested respectively. According to single factor and orthogonal experiment results, the optium experimental conditions were as follows: macroporous resin D301 as adsorbent, acetone as eluent, pre-column concentration 9% , pH value 7.0 of distilled water, flow rate 0.4 L/h. Finally, the best process condition was verified by stability test. Under these conditions, the yield of chestnut shell tannin was up to 82% , and tannin mass fraction was higher than 62%.关键词
