The aim of this work is to study the extractive ability of hydroxamic acids derived from phthalic acid (an aromatic l,2dicarboxylic acid). Thus mono - and di-esters of this acid were synthesized and employed for the preparation of the corresponding hydroxamic acids. Compounds prepared are aminophthalic - anhydride (APA) and mono methyl phthalate 2potassium hydroxyamate (MMPPH) were characterized with different physical and chemical tools. The extractive ability of these compounds towards V(V), Cu(ll), Fe(1I1), Cd(11), Mo(V) and U(VI) were studied under different pH values and the stripping of these metal ions with 2.0M H2S04 is also studied.
