Study of structural parameters on the adsorption selectivity of a molecularly imprinted polymer

This work was focused on the influence of match degree of structure parameters i.e. molecular size, volume and polarity (denoted as R d , V d and P d ) between imprinted cavities in Qu-MIP and Xn on the adsorption selectivity. The results presented that the influence of R d on the adsorption selecti...

Description
Summary:This work was focused on the influence of match degree of structure parameters i.e. molecular size, volume and polarity (denoted as R d , V d and P d ) between imprinted cavities in Qu-MIP and Xn on the adsorption selectivity. The results presented that the influence of R d on the adsorption selectivity was the largest and the most regular, while the influence of P d was the smallest and the most irregular. Besides, the influence degree of V d was decreased in general with the increase of R d . However, as R d was in the threshold of [0.99, 1.02], V d would rise to the major influence factor. Furthermore, utilizing data obtained from experiment, the influence authority of R d , V d and P d on the adsorption selectivity was calculated theoretically through multiple linear regression and principal component analysis of IBM SPSS Statistics 20, and results showed the authority order was R d , V d and P d at any circumstance despite the value was different, which was in accordance with the result we directly inducted from the experiment.
