Description
Summary:A graphite furnace atomic absorption spectrophotometer (GFAAS) with Zeeman-effect background correction has been used for the determination of nickel and copper at very low level concentrations in a 30% ( w v ) solution of zirconium fluoride. Using palladium nitrate and nitric acid as matrix modifiers, the detection limits for nickel and copper were determined to be 6.3 and 3.2 ng/g, respectively. A specially made graphite platform was used for this study because it was found to withstand the drastic conditions of analysis for a longer period of time than a graphite tube alone. The technique has been validated by recovery studies on spiked samples and by comparing the slopes of standard addition and calibration curves. The precision of the procedure was significant and the relative standard deviation Was
