1. A process for the preparation of an ordered mesoporous sorbent comprising:

  • (a) mixing an imprint coating precursor and an ordered mesoporous substrate to form a coated mesoporous substrate wherein the imprint coating precursor comprises a template molecule bound to one end of more than one bifunctional ligand;

    (b) treating the coated mesoporous substrate with an acid solution;

    (c) evaporating the mixture; and

    (d) titrating the coated mesoporous substrate to a neutral pH to form the ordered mesoporous sorbent.
