THE STUDY ON ADSORPTION AND DE-ADSORPTION BEHAVIOR OF SOME BIOMARKERS ON DIFFERENT TYPE-Y CHINESE MOLECULAR SIEVES

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.
