Abstract |
Adsorptive removal of benzotriazole (BTA) and benzimidazole (BZI) using a Co-based metal azolate framework, MAF-5(Co), has been studied to understand the applicability of MAF in the removal of toxic water pollutant from contaminated water. The adsorption capacity of the MAF-5(Co) for BTA and BZI was highest than that of commercial activated carbon with other typical adsorbents including metal–organic frameworks (MOFs), even though the porosity of MAF-5(Co) was the lowest among the tested adsorbents. The remarkable adsorption of MAF-5(Co) was explained by hydrophobic effect and π-π interactions between the BTA and MAF-5(Co). Based on the zeta potential of MAF-5(Co) and effects of solution pH on the BTA adsorption, electrostatic interactions between the MAF-5(Co) and BTA species might also affect the adsorption of BTA over MAF-5(Co). Moreover, MAF-5(Co) can be regenerated by simple ethanol treatment and is reusable for adsorptive removal of BTA. Therefore, MAF-5(Co) can be suggested as a potential adsorbent for BTA and BZI removal from water based on their facile synthesis, highest adsorption capacity and excellent reusability.
Keywords: adsorption; benzotriazole; benzimidazole; MAF-5(Co); water pollutant.
