    Abstract: The reagent (S)-5-methoxy-2-[[(4-methoxy-3, 5-dimethyl-2-pyridinyle-methyle] sulfinyle]-1H-benzimidazole gives greenish yellow coloration with V (V) as well as Co (II) in basic medium. This observation is used for the simultaneous determination of both the metal ions using Zero and second order derivative spectrophotometry. Optimum conditions were ... Show More

    Abstract: Esomeprazole is a new chromogenic reagent used for the determination of nickel (II) by direct spectrophotometric method. Esomeprazole forms a greenish yellow colouredcomplex with nickel (II) at pH 5. The method obeys Beer’s law over 0.139 – 1.394 μg mL-1, Sandell’s sensitivity is0.0029mg/cm2and molar absorptivity value (ε = 2.5 x 104 L mol-1cm-1) .... Show More
