In this study, magnetized MOF-74 (Ni) was prepared using an ultrasound-assisted synthesis method. This novel functional magnetic adsorbent was characterized using various techniques. Using the prepared material as adsorbents, a magnetic solid-phase extraction method coupled with high-performance liquid chromatography was
