**5. Reusability**

MIPs sorbents are easily regenerated by washing with organic solvents to remove the adsorbed compounds. Therefore, they can be applied for various extractions repeatedly. In this aspect, acetylsalicylic acid MIP successfully adsorbed (removal efficiency 75–78%) the target compound from acidic aqueous solutions six times [55]. After desorption, MIP was regenerated with a mixture of methanol and acetic acid (7:3, v/v) followed by methanol. There are numerous examples of reusability in literature that include those cited in **Table 3** for the MIPs prepared for selective extraction of acetylsalicylic acid [55], diclofenac [36] and multitemplates (ibuprofen, naproxen, ketoprofen, diclofenac and clofibric acid) [26]. Such work, clearly demonstrate that MIP can be reused many times without losing its adsorption capacity. This is an excellent advantage for MIP as it is a common knowledge that many adsorbents are discarded after a single use.
