Özet:

 

The use of chemically modified XAD-4-1,2-bis  (o-aminophenylthio) ethane chelating resin for preconcentrating  Cr6+, Mn2+, Fe3+, Co2+, Cu2+, Cd2+, Zn2+,  Pb2+, and Ni2+ was studied using flame atomic absorption  spectrometry (FAAS) for metal monitoring in environmental samples.   Cd2+, Zn2+, Pb2+, and Ni2+ ions were quantitatively  recovered at the rate of 96.0%, 101.0%, 101.0%, and 95.0%, respectively  (RSD < 5%), from the studied solutions.  The procedure is based on  the retention of analytes on a short column of 1,2-bis  (o-aminophenylthio) ethane-XAD-4 chelating resin from a buffered  sample solution and subsequent elution with 1 M HNO3.  Various  parameters, such as pH, eluent type, and concentration, flow rate of  sample solution and matrix interference effect on the retention of the  metal ions have been studied.  The optimum pH for the sorption of the  above-mentioned metal ions was about 6.  The adsorption and batch  capacity of adsorbent and loading half time (t1/2) for Ni2+,  Zn2+, Cd2+, and Pb2+ were established.  The limit of  detection was 3.0 m g L-1 for Pb2+ and Ni2+, 0.6 m g  L-1 for Cd2+, and 0.3 m g L-1 for Zn2+.  The validation  of the procedure was carried out by analysis of certified reference  materials and standard addition.  The proposed enrichment method was  applied to environmental samples from Trabzon.
