Abstract Porous carbons have been very useful in versatile applications in various fields, and several precursors were used for such carbons. Recently metal-organic frameworks (MOFs) are also widely used as precursors for porous carbons. In this study, porous carbons were obtained by high temperature pyrolysis of metal azolate framework-6 (a subclass of MOFs), especially in the co-presence of KOH activator. The porosity and defect concentration of carbon increased by adding KOH activator; and therefore, the obtained carbon might be very useful in adsorptions. Actually the carbons obtained in suitable condition showed huge adsorption capacity for wide range of pharmaceutical and personal care products (such as acidic ibuprofen; weakly acidic triclosan and oxybenzone; and basic diclofenac sodium and atenolol). A plausible adsorption mechanism for ibuprofen could be also suggested by adsorption in wide pH conditions. Moreover, the used carbon could be recycled easily by solvent washing. Therefore, metal azolate framework-6-derived carbon (especially in the co-presence of KOH activator) could be suggested as a potential adsorbent to purify water contaminated with organics such as pharmaceutical and personal care products.
