Abstract:
Nickel (Ni) is toxic effect on human body and must be determined
in human blood samples. In this study, Ni ions separated
and preconcentrated from blood samples based on magnetic
Fe۳O۴-supported amine/amide-functionalized graphene oxide
(Fe۳O۴@A/A-GO) nanoparticles by dispersive sonication micro
solid phase extraction (DS-μ-SPE). By procedure, ۱۰ mg of
Fe۳O۴@A/A-GO was dispersed in ۱۰ mL of human blood samples
with sonication for ۵.۰ min and then separated from liquid phase
with magnetic accessory. The Ni ions was extracted based on
amine/amide covalence bonding of Fe۳O۴@A/A-GO sorbent
(Ni---: NH۲). Then, the Ni ions back-extracted from Fe۳O۴@A/
A-GO in low pH with nitric acid (۰.۲ mL, ۰.۳ M) which was
diluted with DW up to ۰.۵ mL and finally, was determined by
ET-AAS (peak area). The LOD, linear range (LR), enrichment
factor (EF) and absorption capacity (AC) were obtained ۳۵ ng
L-۱, ۰.۱۵ -۷.۲ μg L-۱, ۱۹.۸ and ۱۳۱.۶ mg g-۱, respectively. The
method was validated by spiking samples.
