چکیده

A novel, simple, sensitive and effective method has been developed for removal of Mo(II) on the superparamagnetic adsorbent as Fe@Mg-Al LDH adsorbent. Spectrometry was used to track the effects of Fe@Mg-Al LDH dose, pH extraction, and contact duration on Mo(II) removal from sample water. This research also looked at adsorption isotherm models for the sorption of Mo(II). The magnetic Fe@Mg-Al LDH adsorbent Mo(II) adsorption capability was 29.74 mg/g respectively. The Freundlich isotherm model fits the removal of Mo(II) utilizing magnetic Fe@Mg-Al LDH adsorbent. This approach has an outstanding linear range of 0.5-26 mg/L for Mo2+ ions. The limits of detection (LODs) for Mo2+ ions adsorption by magnetic Fe@Mg-Al LDH adsorbent were reached by utilizing a signal-to-noise ratio of 3 (LOD= 2.35 μg/L). These findings show that magnetic Fe@Mg-Al LDH adsorbent is an effective adsorbent for extracting Mo(II) from different sample waters.
