Introduction of Dispersed Solid Extraction Method Based on Magnetic Adsorbent withOctadecylamine to Extract Cu (II) and Cd (II) Ions from Dairy Products

In this study, a brand-new, very effective adsorbent was created for the extraction of magneticallydistributed solid phase. Octadecylamine and Fe۳O۴ were co-precipitated to create the adsorbent. Finally, aflame atomic absorption device was used to study the enriched analytes. The detection limits of the abovemethod for Cu (II) and Cd (II) were ۰.۸۵ and ۰.۵۶ μg/L, respectively, under ideal conditions. Cu (II) and Cd (II) ionshad a linear range of ۲۰۰-۲.۳ and ۱.۵-۲۰۰ μg/L, respectively. Copper (II) and cadmium (II) showed enrichmentfactors of ۲۷.۰ ± ۰.۷ and ۲۶.۵ ± ۰.۸ and extraction efficiency of ۹۶.۳ ± ۲.۶% and ۹۴.۶ ± ۲.۸%, respectively.
