| Abstract | ||
| Metal complexes of 3-phenyl-1-(2-hydroxyphenyl)-2-propene-1-one with Al (III) and Ga (III) ions in 95% ethanolic solution have been prepared and studied . Ligand to metal ratio for the complexes has been investigated using the mole ratio method. The 3:1 complexes absorb light in the region 200-600 nm. Formation constant also have been determined using corresponding solution method.The spectrophotometric investigation of the metal complexes indicated that the detection limits were 0.97x10-6 M of Al (III) and 1.35x10-6 M of Ga (III) ions with linear calibration curves up to 3.0x10-4 M for both ions. No interferences were noticed with most transition metal under our experimental conditions. | ||
