- Abstract
A facile and efficient ultrasound-assisted dispersive microsolid-phase extraction (UA-D-μSPE) method was successfully used for determination of trace amount of Cd(II) by using Fe3O4@hydroxypropyl methylcellulose (Fe3O4@HPMC) adsorbent. The flame atomic absorption spectrometry (FAAS) was used for Cd(II) determination. The Fe3O4@HPMC nano-composite was characterized using the pHpzc value, BET, FT-IR, TEM, XRD, and VSM analysis. The factors influencing the extraction efficiency including pH, eluent type, sorbent dose, extraction time, desorption time, and sample volume, were optimized. The enrichment factor (EF), the limit of detection (LOD), and relative standard deviation (RSD) are 50, 0.4 ng mL−1 and below 4.2%, respectively. Comparing the findings of this study with other studies, adsorbent showed excellent adsorption performance and had the advantages of ease of preparation and recycling. However, the proposed accurate method can detect trace Cd(II) amounts from different real samples such as wheat, beans, fruit, and fruit juice samples with complex matrices.
