| Abstract | ||
| A 2-[(6-Methoxy-2-Benzothiazolyl)azo]-4-methoxyphenol (MBTAMP) ligand was used to determine Co2+ and Ni2+, the chelating complexes of these ions with (MBTAMP) ligand were also prepared using mole ratio and continues variation methods, metal to reagent were (1:2) for two complexes. The complexes were identify by using UV-Vis spectrophotometry and (FTIR) spectra. The wavelengths of maximum absorption of two complexes are (512 nm) and (605 nm) for Co-MBTAMP and Ni-MBTAMP respectively. The optimum condition of pH and temperature were studied, the molar absorbitivty (ε) was 3.84x 104 L.mol-1.cm-1, 3.9 x 104 L.mol-1.cm-1 for Co2+ and Ni2+, detection limit was (0.0002), (0.0010) ppm, The interferences of ions, and suitable masking agents for two complexes was studied. | ||
