Özet
A novel dispersive solid phase microextraction (dSP-ME) technique using activated carbon cloth (ACC) and layered double hydroxide (LDH) has been developed for enriching and extracting Pb(II) and Ni(II). The ACC@MnCoAl-LDH nanosorbent, has proven with high surface area, superior extraction dynamics and efficiency, compared to traditional sorbents. Structural features of the new ACC@MnCoAl-LDH sorbent were also characterized. Analytical parameters such as pH, adsorbent quantity, sample volume, eluent volume, adsorption/desorption time, and concentration were optimized, using 7.5 mg of adsorbent. Limit of detection (LOD), limit of quantification (LOQ), and preconcentration factor (PF) were determined at 0.71 μgL -1, 2.35 μgL −1 and 25 for Pb(II) and 0.07 μgL -1, 0.22 μgL −1 and 30 for Ni(II). Validation tests also performed using certified reference materials (CRMs). The % RSD was calculated at 2.5–7.8 for Pb(II) and 3.5–8.2 for Ni(II). The method was applied to determine Pb(II) and Ni(II) levels in packet juices, noodles, and water samples.
