Abstract

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.
