| Abstract | ||
| In this study used graphite furnace amtomic absorption for determination of the trace heavy metals (As, Cr, Pb, and Cd) in natural water samples after collection and concentration by chelating resin disk . A miniature filtering apparatus was improved to be able to use 6 mm diameter chelating resin disk . Collection of heavy metals in 25 ml of sample solution was finished within 10-25 min by suction and elution was accomplished within 15 min by ultra sanitation . For the elution relatively dilute acid concentration 0.2 M HNO3. Several metals, As , Cr, Pb and Cd could be determined. | ||
