TheA simple, rapid and sensitive spectrophotometric method has been developed for the determination of Cu (II) by using N-BenzoylAbstract
Thioureathiosemicarbazonesynthesized and characterized by elemental and analysis. MAAPHE extractsCu(II) quantitatively(99.5%) into chloroform from an aq. solution of pH range 5.5-6.5 . The chloroform extract shows an intense peak 450nm (max). Beer’s law is obeyed over the Cu(II) concentration range 0.1-4.2 μg/ml. The Sandell’s sensitively and molar absorpitivity for Cu-MAAPHE system is 0.00252μg cm-2 and 25700 L/mol/ cm respectively. The composition of extracted species are found is 1:2 (Cu:MAAPHE) by Job’scontinuous variation and mole ratio method. Interference by various ions has been studied. The proposed method has
been successfully applied for determination of Cu(II) in alloy
