| Abstract | ||
| Method described spectrophotometric determination of mercury metal ion Hg (I) by chelate with the reagent 5- (6-Bromo-2- benzothiazolyl) azo]-4-hydroxyBenzoic acid ( 6 -BrBT ABA) , to form Yellowish complex with maximum absorption at Max 523nm at the optimum conditions, pH ( 5.5-9.0 ) , concentration reagent ( 1 10-3M) ,temperatures ( 20 -30 ) Ċ and time ( 10 min) , Beer's law was obeyed in the concentration range between (1-11) μg.ml-1 with molar absorptivity ( 5.11 103) L.mol-1.cm-1 . and detection limit ( D.L.) is 0.02μg.cm-1 . the percentage relative error ( E rel %) 1.23, Percentage recovery ( Rec%) 96.57 for assessment of the selectivity of the method , a ratio of metal to ligand was determined by using molar ratio method and continuance variation method . Also , the complex is characterized by using u.vvisible spectral , IR- spectra and elemental analysis | ||
