ABSTRACT Due to the abundant SiO 2 and Al O 3 content in coal gangue (CG), synthesis of zeolite from CG has become a route realize high‐value utilization CG. However, some impurities contained CG, such as iron oxide carbon, have an adverse impact on crystallization application zeolites. In this work, we propose strategy directly convert into magnetic without need for external source. Carbon is calcined situ reduce magnetite. This followed by hydrothermal reaction synthesize A. Effects m (NaOH)/ alkali fusion temperature, time zeolites are investigated. The synthesized A exhibits cubic morphology with rounded corners, having particle size about μm. maximum adsorption capacity removal ratio Cu 2+ 91.74 mg/g 98.50%, respectively. solid–liquid separation test after shows that could achieve accelerated within 15 min. work provides pathway comprehensive demonstrates good adsorbent practical highly efficient separation.
