4DescriptionAbstract The complexation equilibria of oximes including 1-phenyl-2-(quinodin-2-yl) ethanoneoxime (pqeo), 2-acetophenone oxime (apo) and 3-nitro benzaldoxime (nbo) with some transition and heavy metal ions such as Cu2+, Co2+, Ni2+, Zn2+, UO22+ and La3+ were studied by potentiometric method in water-dioxane mixed solution. All of the titration steps were carried out at 25.0▒0.1 C and ionic strength (Á) of 0.1 M supported by KNO3. The overall stability constants log▀ of respective species were evaluated by computer refinement of the corresponding potentiometric pH titration data using BEST computer program. The corresponding distribution diagrams were depicted as a function of pH by using HySS2009 program. The most likely species were obtained from distribution diagrams and the effect of the oximes structures on the stability constant values were investigated.
