Direct Spectrophotometric Determination of Ni (II) Using Esomeprazole
نویسندگان
چکیده
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 is 0.0029mg/cm 2 and molar absorptivity value (ε = 2.5 x 10 4 L mol -1 cm -1 ). The method is useful for determination of nickel in in groundnut seeds and sesame seeds was determined by the following procedure.

: A rapid, simple,sensitive and selective direct spectrophotometric method has been developed for the determination of nickel(II) in various real samples. 5-Bromo-2-hydroxy-3-methoxy benzaldehyde-p-hydroxybenzoic hydrazone reacts with Ni(II) forming green coloured soluble complex [ ( Ni(II)-5-BHMBHBH] in basic buffer solution. The maximum absorbance was observed in the pH range 5.5-7.5 and Ni(I...

A direct spectrophotometric method for simultaneous determination of Co(II) and Ni(II), with diethanoldithiocarbamate (DEDC) as complexing agent, is proposed using the maximum absorption at 360 and 638 nm (Co(II)/DEDC) and 390 nm (Ni/DEDC). Adjusting the best metal/ligand ratio, supporting eletrolite, pH, and time of analysis, linear analytical curves from 1.0 10-6-4.0 10-4 for Co(II) in the pr...

A Simple, accurate and reproducible spectrophotometric method by Hydrotrophic Solubilisation was developed for the estimation of Esomeprazole. In the present investigation, hydrotropic solution of urea (10M) was employed as a solubilising agent to solubilise the poorly water soluble drug, esomeprazole in the tablet form and determined with the help of spectrophotometric determination in ultravi...
متن کاملDetermination of mercury (II) by spectrophotometric method based on self assembly of gold nanoparticles
Due to the binding of the –COO- group with the mercury (II), gold nanoparticlesfunctionalized with glutathione can self-assemble to form a supermolecular network in the HAc-NaAc buffer solution. The aggregation of functionalized gold nanoparticles and mercury (II)caused the shift of maximum absorption peak of the UV-Vis spectrum from 520 nm to 609 nm.Based on this principle, a simple spectropho...
