  Two novel ligands, (E)-N1-(2-hydroxy-5-nitrobenzlidene) isonicotinoylhydrazone (HNBISNH)/2-(4-fluoro benzlideneamino)benzenethiol (FBBT) were synthesized and used for the quantification of copper (II) in various water and c HNBISNH/FBBT interacts with copper (II) to form 1:1 [L:M] orange /brick red color complexes in presence of phosphate buffer of pH 3.7/4.5 which increases the sensitivity of the complexes. Thus formed colored complex followed the Beer’s law up to 1.6 and 1.9 mg L‑1 with an optimum concentration range over 0.11-1.3 mg L-1 and 0.10-1.7 mg L-1, the slope of Ringbom’s plot are found to be 0.3500 and 0.3300 for copper(II)-HNBISNH and copper(II)-FBBT complexes, respectively. The molar absorptivity and Sandell’s sensitivity of copper (II)-HNBISNH and copper(II)-FBBT complexes were calculated and found to be 4.91&tim.. Read More»
