In this method, a few microliters of organic solvent (40.0\u2009\u00b5L carbon tetrachloride) was transferred to the bottom of a conical sample cup. Then 10.0\u2009mL of aqueous solution was transformed to fine droplets while passing through the organic solvent. At this stage, metal\u2013ligand hydrophobic complex was extracted into the organic solvent. After extraction, 20\u2009\u00b5L of extraction solvent was injected into the graphite tube using an auto\u2010sampler.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS<\/jats:title>\n                    <jats:p>\n                      Under optimal conditions, enrichment factors and enhancement factor were in the range of 180\u2013240 and 155\u2013214, respectively.
