Trace elements are naturally found in the
structure of soil and water. However, today, environmental pollution affects
living things negatively. While trace elements such as chromium, cobalt,
copper, iron, nickel, manganese and zinc play important roles in human
metabolism, some trace elements such as lead, cadmium, arsenic and mercury
should not be taken into the body at all. The deficiency or excess of trace
elements taken into the body causes various diseases. The determination of
these elements at very low levels is achieved by analytical methods. Solid
phase extraction method is a sensitive, fast and economical method that is
widely used in the effective and accurate analysis of trace elements in real
samples (Amit, Bhadauria, Singh, Lodhi, Chaturvedi, & Tomar, 2010; Daşbaşı,
Muğlu, Soykan & Ülgen, 2018; Lavilla, Cabaleiro, Costas, Calle & Bendicho, 2009).
We
synthesized a new ternary polymer, polystyrene/polyacrylonitrile/polyindole
(PSt/PAN/PIN) for solid phase ectraxtion method (SPE). The structure of polymer
was characterized by FTIR, BET, SEM,
X-RD, AFM and TGA technique. A SPE method was developed for the enrichment of
chromium (III), copper (II), iron (III), manganese (II), lead (II) and zinc
(II). The synthesized ternary polymer as solid phase was used. The adsorption
capacity were found in the range of 39.9 − 56.7 mg g-1 and the
detection limits of analytes were
obtained in the range of 0.9 − 2.0 μg L-1. The preconcentration
factor of method was calculated as 100. Relative standard deviation was found
at ≤ 3.3% (n=11). Firstly, the developed SPE method was applied to standard
reference material, and than some food samples. The trace elements were
analyzed by flame atomic absorption spectrometry.
