| Abstract | ||
| Sensitive extraction method is used for separation preconcentration coupled with spectrophotometric determination of Zinc(II) and Nickel(II) as chloro anions from acidic HCl media by using crystal violet after formation ion pair association complex after studied the optimum condition for extraction demonstrated 1.5M HCl for Zn +2 and 1M HCl for Ni 2+ , with 50 µg Zn 2+ and Ni 2+ , 0.7mL 1% TritonX-100 for extraction ion pair association of Zn 2+ as well as 0.9mL with Ni 2+ and 80 0 C suitable for formation CPL and extraction ion pair complex for both metal ions ,with 10 minutes of heating in thermostatic water bath for Zn 2+ and 15 minutes for Ni 2+ then study involved effect of interferences and electrolyte with spectrophotometric determination in different samples. The wave length for maximum absorbance of ion pair complex extracted was λmax=590nm for Zn 2+ and 595nm for Ni 2+ complexes | ||
