Green synthesis of melamine-based covalent-organic framework@ZIF-۸ as efficientsorbent for Cr(VI) removal from water

Chromium (Cr) ion is one of the most common and dangerous metal pollutants in the environment,which is widely used in various industries. In this study, the composite consisting of melamine-based COF andZIF-۸ was synthesized via the mechanochemical method. Then, the performance of melamine-based COF andZIF-۸ and the resulting composite was evaluated to remove Cr(VI) from an aqueous solution with a concentrationof ۱۰۰ ppm. The results showed that the prepared composite performs higher in Cr(VI) adsorption compared tomelamine-based COF and ZIF-۸ in mild conditions
