Özet:

 


                        A new sensitive and accurate solid-phase extraction 
method for preconcentration of trace amounts of cadmium and lead in various 
environmental samples prior to flame atomic absorption spectrometry 
determination has been developed. The proposed method is based on the 
utilization of multiwalled carbon nanotubes in combination with 
5-benzyl-4-[-chlororbenzylidene amine]-4H-1,2,4-triazole-3-thiol (BCBATT) as 
a solid-phase sorbent with the aid of ultrasonication. The effect of the 
preconcentration parameters was investigated. Good recoveries ranging from 
95% to 102% with relative standard deviations of 3.2% and 2.8% 
for Cd2+    2  +   2+2+^{2+} and Pb2+    2  +   2+2+^{2+}, respectively, were obtained, indicating high 
accuracy and precision. The limits of detection were 0.2 and 0.5 μ μ  μμ\mu g/L 
for Cd2+    2  +   2+2+^{2+} and Pb2+    2  +   2+2+^{2+}, respectively. The preconcentration factor was 
100. The validation of the proposed preconcentration procedure was performed 
using certified reference materials with satisfactory and compatible 
results. The proposed method was applied to various real environmental 
samples for determination of Cd2+    2  +   2+2+^{2+} and Pb2+    2  +   2+2+^{2+} concentrations and 
satisfactory results were obtained.
