adsorbent properties. A simple, low cost, sensitive and selective
solid phase extraction method was developed for the determination
of heavy metals in water, beverage and food samples.
Presented PHB-DEA column solid phase extraction procedure
may be alternative with respect to both preconcentration factor
and detection limit to literature values. Adsorption capacity of
PHB-DEA polymer was found higher than other adsorbent reported
in the literature (Roushani, Abbasi, Khani, & Sahraei, 2015; Zhang,
2013). Developed method can be applied to water and food
samples which are contain highly saline and complex matrix for
the determination of heavy metal ions.
