【摘要】 首次对不同120型号的国产Y型分子筛对生物标记化合物甾烷和藿烷等的柱层析吸附—脱附行为进行了研究。通过实验发现:USY,DNSY和DASY分子筛对甾烷、藿烷具有相同的吸附,不能用于甾烷、霍烷的分离;CDY分子筛对不同构型的甾烷、藿烷具有不同的吸附,但对C29藿烷和C295α,14α,17α—20R甾烷吸附能力近似;MOY和REUSY分子筛对藿烷具有很强的吸附,而对甾烷、伽马蜡烷、β—胡萝卜烷吸附较弱,可富集分离出甾烷、伽马蜡烷、β—胡萝卜烷;NaY分子筛对不同构型的甾烷、藿烷、伽马蜡烷、β—胡萝卜烷吸附的差异性明显,是分离富集甾烷、藿烷等生物标记化合物的最佳选择。更多还原

【Abstract】 This paper investigates the column chromatographic adsorption and de-adsorption behavior of different type-Y Chinese molecular sieves on some biomarkers(e.g.steranes,hopanes).USY molecular sieve and DNSY molecular sieve and DASY molecular sieve to the steranes and hopanes have the same adsorption and de-adsorption,which can’t be used for the separation of steranes and hopanes.CDY molecular sieve to the different configurations of steranes,hopanes has the different adsorption,but to the C29 hopanes and 5α,14α,17α-20R C29 steranes,CDY sieve has similarity adsorptive capability;The MOY molecular sieve and the REUSY molecular sieve have very strong adsorption to hopanes,but weak to the steranes,the gammarane,β-carrotane adsorption,which can enrich the steranes,the gammarane and β-carrotanes;The NaY molecular sieve has the different adsorption behaviors to the different configurations of steranes,hopanes,gammarane and β-carrotane,which is maybe the best type-Y Chinese molecular sieve to separate steranes,hopanes,gammarane and β-carrotane.更多还原
