Abstract Co-based metal azolate framework, MAF-5(Co) has been utilized to understand the applicability of MAF in the water purification for the removal of toxic water pollutant, benzotriazole (BTA) and benzimidazole (BZI) from water. The adsorption capacity of the MAF-5(Co) for BTA and BZI was highest than that of other typical adsorbents including commercial activated carbon and metal–organic frameworks (MOFs). The highest adsorption of MAF-5(Co) was explained by hydrophobic effect and π-π interactions between the BTA and MAF-5(Co). Electrostatic interactions between the MAF-5(Co) and BTA species might also affect the adsorption of BTA over MAF-5(Co) considering the zeta potential of MAF-5(Co) and effects of solution pH on the BTA adsorption. Moreover, MAF-5(Co) can be regenerated by simple ethanol treatment and is reusable several times for the removal of BTA. Therefore, MAF-5(Co) can be recommended as a potential adsorbent for BTA and BZI removal from water considering facile synthesis, highest adsorption capacity and excellent reusability.
