A facile method to improve the feasibility of water‐unstable metal–organic frameworks in an aqueous environment has been developed that involves imbedding in a polymer monolith. The effect of compartment type during polymerization plays a significant role in maintaining the crystalline structure and thermal stability of the MOFs, which was confirmed by powder X‐ray diffraction (PXRD) and thermogravimetric analysis (TGA), respectively. The MOF–polymer composite prepared in a narrow compartment (column, ID 0.8 mm) has better thermal and chemical stability than that prepared in a broad compartment (vial, ID 7 mm). The developed MOF–polymer composite was applied as an adsorbent in solid‐phase microextraction of nine non‐steroidal anti‐inflammatory drugs (NSAIDs) and could be used for extraction more than 30 times, demonstrating that the proposed approach has potential for industrial applications.
