Determination of Trace Amounts of Palladium in Water Samples by Graphite Furnace Atomic Absorption Spectrometry after Dispersive Liquid-Liquid Microextraction
Figure 3
Effect of the volume of extraction solvent (CHCl3) on the enrichment factor and extraction recovery of palladium obtained from DLLME. Extraction conditions: water sample volume, 5.0 mL; disperser solvent (methanol) volume, 500 μL; TMK concentration, 1.0 × 10−3 mol L−1; concentration of palladium, 0.4 μg L−1; pH = 3.0.
