Özet
Matricaria chamomilla L. , referred to as chamomile, is a well-known medicinal plant that is widely distributed throughout the world. In this study, a novel NiO-SnO2 nanocomposite- assisted preconcentration method was established for efficient extraction and separation of manganese ions from chamomile tea extract. This preconcentration method was coupled with flame atomic absorption spectroscopy (FAAS). NiO-SnO2 nanocomposites were synthesized using simple one-pot co-precipitation procedure and calcined at 650 °C to obtain nanoparticles with sizes below 100 nm. X-ray diffraction (XRD) analysis indicated that the crystallite size of NiO-SnO2 nanocomposites was estimated to be 46.03 nm using the Monshi–Scherrer equation. The LOD (limit of detection) and linear working range were determined as 3.6 μg/L and 10–100 μg/L, respectively. The proposed method was successfully validated, and recoveries ranged from 87.2 %–117.0 %. NiO-SnO2 nanocomposites represent a promising low-cost adsorbent for the preconcentration and subsequent determination of other heavy metal ions in diverse herbal extracts.
