摘要: 以ZSM-5分子筛、阳离子交换树脂、大孔吸附树脂作为吸附剂,选择传统药用植物忽地笑中石蒜碱和加兰他敏作为吸附质,研究了分子筛对两种生物碱的吸附及解析效果,并与两种树脂吸附效果进行对比,进一步研究了分子筛对两种生物碱的吸附动力学。研究结果表明:ZSM-5分子筛对石蒜碱及加兰他敏的吸附和解析的综合效果最佳,吸附率均在99.50%以上,解析率分别达到90.35%和84.34%;阳离子交换树脂D-001、HD-8对两种生物碱的吸附率较高,但解析率仅为75%左右;大孔吸附树脂D-101、AB-8对石蒜碱的吸附率较高(均为95%左右),但对加兰他敏吸附效果欠佳,吸附率仅为14.50%和20.56%。静态吸附动力学研究发现:ZSM-5分子筛对石蒜碱及加兰他敏的吸附符合准二级动力学模型,R2值均达到0.999 9,表明化学吸附起主要作用。

Abstract: In order to evaluate the adsorption and purification capability of ZSM-5 molecular sieve on the lycorine and galanthamine, the adsorption and desorption performance of the three adsorbents (including ZSM-5 molecular sieve, cation exchange resin, macroporous resin) on the lycorine and galanthamine from Lycoris aurea were investigated, and then the adsorption kinetics were also studied. The results showed that ZSM-5 had obvious advantages in adsorption and elution of lycorine and galanthamine compared with macroporous resin (AB-8 and D-101) and cation adsorption resin (D-001 and HD-8). Adsorption rates of lycorine and galanthamine on ZSM-5 achieved more than 99.5% and the elution rates achieved 90.35% and 84.84%, respectively. The adsorption rates of D-101 and AB-8 were high, but the elution rates were only about 75%. Adsorption rates of lycorine on D-101 and AB-8 were high, but those of galanthamine were only 14.50% and 20.56%. The result of kinetics study indicated that the adsorption of lycorine and galanthamine on ZSM-5 was in good consistent with the second order kinetics model (R2=0.999 9), and chemisorption occupied the leading role.
