Objective:
To optimize the polymerization conditions of vinblastine (VLB) imprinted polymer.
Methods:
The conditions were optimized by the method of uniform design. The major factors investigated included the amount of functional monomer (MAA) and the cross-linker (EDMA) and the progenic solvent (toluene or acetonitril). The adsorption rate of VLB on the solid-phase extraction (SPE) column packed with MIP was adopted as the response value.
Results:
The optimal conditions were MAA 0.4 mmol, EDMA 1.6 mmol and using acetonitrile as the solvent. Under the conditions,the VLB imprinted polymer was synthesized and the absorption rate of VLB was 88.20%. The characterizations of the optimal MIP were determined by IR spectrometry and scanning electron microscope (SEM) analysis.
Conclusion:
It is possible to furtherly improve the nature of the polymer by optimizing the polymerization parameters with uniform design. The polymer synthesized under the optimal conditions exhibited high affinity to the target molecule VLB.
