admium is an important constituent widely used in different
industrial processes for production of various synthetic
materials. For evaluation of workers’ exposure to trace toxic
metal of Cd (II), environmental and biological monitoring are
essential processes, in which, preparation of samples is one
of the most time-consuming and error-prone aspects prior to
analysis. To evaluate factors influencing quantitative analysis
scheme of cadmium, solid phase extraction usingmini columns
filled with XAD-7 resin was optimized regarding sample pH,
ligand concentration, loading flow rate, elution solvent, sample
volume (up to 500 ml), elution volume, amount of resins,
and sample matrix interferences. Cadmium ion was retained
on solid sorbent and was eluted with 2M HNO3 followed by
simple determination of analytes by using flame atomic
absorption spectrometery. Obtained recoveries of metal ion
were more than 95%. The amount of the analyte detected after
simultaneous pre-concentration was basically in agreement
with the added amounts. The optimized procedure was also
validated with three different pools of spiked urine samples
and showed a good reproducibility over six consecutive days
as well as six within-day experiments. The developed method
promised to be applicable for evaluation of other metal ions
present in different environmental and occupational samples
as suitable results were obtained for relative standard deviation
(less than 10%), therefore, it is concluded that, this optimized
method can be considered to be successful in simplifying
sample preparation for trace residue analysis of Cd in different
matrices for evaluation of occupational and environmental
exposures.
