HZ818树脂对葡萄籽原花青素的吸附性能
Adsorption Properties of Grape Seed Proanthocyanidins on HZ818 Macroporous Resin
摘要
Abstract
This study was carried out to investigate adsorption properties of grape seed proanthocyanidins on HZ818 macroporous resin. Through static adsorption experiments, we found that the adsorption process was endothermic. The static adsorption capacity of HZ818 macroporous resin for proanthocyanidins was 73.55 mg/g at an initial concentration of 1.07 mg/mL. Adsorption isotherms were plotted each of which could be wellfi tted to Langmiur equation. Fifty percent ethanol revealed the best desorption effect. The dynamic adsorption capacity was 109.13 mg/g at a loading concentration of 1.36 mg/mL and afl ow rate of 2 BV/h. The desorption rate of proanthocyanidins was 93.81% after desorption with a 4-fold BV excess of 50% ethanol at afl ow rate of 1 BV/h.关键词
