Dr. Egbal Eltom Bakheet | Dr. Elmugdad Ahmed Ali
Abstract: The study deals the extractive ability of Phthalohydroxamic acid. The acid was prepared through coupling of the parent ester with the free hydroxylamine. It was characterized by color test, m. p. , infrared and G. C- mass spectrometry. The extractive properties of the acid towards the metal Ni+2 and Co+2 cations were determined under different pH values. The extractability it found to Ni (II) 24.4 % at pH 6 and Co (II) 35.5 % at pH 9
