Özet:

 

Spectrophotometric determination of Ni(II) was carried out  using picolinaldehyde-4-phenyl-3-thiosemicarbazone (PAPT) as a  complexing/chromogenic reagent.  The possibility of using a micellar  system was explored to enhance the degree of detection and allow a  more sensitive spectrophotometric method for the determination of  nickel ions.  The anionic surfactant Triton X-100 greatly enhanced the  molar absorptivity and limit of detection relative to that observed  with bulk water or an organic solvent.  The linear calibration graphs  were obtained for 0.5-2.0 mg L-1 and 0.001-1.0 mg L-1 of Ni(II)  in aqueous and surfactant media, respectively.  Using this approach,  the limit of detection for the PAPT-Ni(II) complex (based on 3 s  of blank absorbance/slope) was found to be 0.0008 mg L-1 with a  micellar enhancement reagent.  The interference from over 50 cations,  anions, and complexing agents was studied at 0.50 mg L-1 of Ni(II);  most metal ions can be tolerated in considerable amounts in aqueous  micellar solutions.
