Abstract
Zianab Tariq, Shaimaa Adnan.
A n organic reagent namely 2-(2-bromophenyl)imino)methyl)-4- (5,6-dimethylpyridin-2-yl)diazenyl)phenol (R) was synthesized" ,characterized" and used for the determination" of copper" after preconcentration using "Dispersive liquid- liquid microextraction(DLLME) .In this precocentration method ,ethanol and acetone were used as extraction and disperser solvents respectively and" the ligand" (2-(2-bromophenyl)imino)methyl)-4- (5,6-dimethylpyridin-2-yl)diazenyl)phenol" was used as a chelating agent for the extraction of" Cu(II),Uv-Vis spectrophotometry was applied for the quantitation of the analyte after preconcentration. The effect of various parameters on the extraction was investigated,such as disperser and extraction solvent type and volume,,pH and concentration of chelating agent.At optimum condition,the enrichment factors of (105) was obtained ,the calibration graph was linear in the range (10-100) μg L-1 Cu +2" with detection limit of" (2.79) μg L-1 and "relative standard deviation" (RSD) for seven "replicate measurements" of 20 μg L-1 of Cu +2 was (1.75)%."The method was applied to the determination of" Cu +2 in some Bee honey samples.
