Synthesis of Zr metal–organic frameworks (MOFs) to remove Fe(3+) from water

Although a trace amount of Fe(3+) is essential for human physiological function, excessive amounts are lethal. Here, we present a protocol for removing Fe(3+) from water through highly crystalline and stable thiol-functionalized Zr metal-organic frameworks (Zr-MOFs). We provide details of the MOFs synthesis and post-functionalization procedures, and include key performance data of the Zr-MOFs for removing Fe(3+), which were collected from the inductively coupled plasma-optical emission spectrometer (ICP-OES) and inductively coupled plasma mass spectrometer (ICP-MS). For complete details on the use and execution of this protocol, please refer to Yuan et al. (2022).
