| description | The concentration of some heavy metals in Bera Lake water samples collected in rainy and
dry seasons has been detem1ined by atomic absorption spectroscopy. The metals in free state,
bound to humic substances; and suspended particles, were fractioned according to a scheme
developed. The metals were pre-concentrated on columns (1 x 10 em) packed with prepurified
Amberlite XAD-16 resin. The concentrations of the metals bound to humic
substances and of free metal ions were detennined after sorption-elution on the resin. The
method optimized with sodium tetraborate reagent was used in detennining the free metal
ions. Meanwhile, the concentrations of metal bound to suspended patticles were detennined
after filtration, dissolved in concentrated nitric acid, centrifugation, and evaporation.
The linearity of the detector response for the concentrations range of 0 - 2.0 ppm was
excellent with a con·elation coefficient ranging between 0.998- 0.999. The recoveries ranged
between 99.5- 100% with a RSD of 0.5- 1.5%. The concentration of elements found in Bera
Lake water ranged: Cu (II), 0.001 ± 0.000 mg/L to 0.309 ± 0.002 mg/L; Cd (II), 0.067 ± 0.002
mg/L to 0.163 ± 0.002 mg/L; Pb (II), 2.613 ± 0.012 mg/L to 10.712 ± 0.025 mg/L; Ni (II),
0.012 ± 0.020 mg/L to 0.224 ± 0.007 mg/L; Cr (III), 0.002 ± 0.006 mg/L to 0.114 ±
0.002mg/L. |
