Özet
Manganese ferrite (MnFe2O4) nanoparticles-assisted dispersive solid-phase extraction (MF-DSPE) was developed for the determination ofrhodium (Rh) in soil samples at low levels with good accuracy andprecision by flame atomic absorption spectrometry (FAAS). The syn-thesis of MnFe2O4nanoparticles was carried out in a microwave sys-tem by a rapid procedure. The pH, buffer volume, sorbent mass,sample volume, eluent volume/concentration, and mixing time wereidentified with univariate optimization. Under the optimal conditions,the limits of detection (LOD) and quantitation (LOQ) were 4.4 and14.7mgL 1, respectively. The sensitivity was improved by 121.9-foldbased upon comparison of the limits of detection with and withoutpreconcentration. The applicability was investigated by spiking rho-dium into soil extracts, and good recovery results between 91.2%and 122.2% were achieved using matrix matching calibration. Theresults showed that MF-DSPE-FAAS determines low levels of rhodiumin soil with good accuracy and precision.
