查询词典 hydrogen

The recognition capability and adsorption rate of MIP can be significantly enhanced by selective modification.Separation factor could be increased from 1.60 to 3.06 after modification when naringenin was chosen as competitive molecules, and the time needed for adsorption equilibrium could be reduced from 100 min to 60 min.Within a certain range, increasing template molecule concentration or diazomethane dosage, or adopting solvent which had weaker hydrogen bond action with template molecules could all improve the modification effect.
