Colorimetric Estimation of Ni(II) Ions in Aqueous Solution
A rapid and accurate colorimetric method has been proposed for the estimation of nickel(II) in aqueous solution. It is found that nickel(II) ions have maximum absorbance at 393 nm in distilled water and in aqueous sucrose solution (0.3 mol dm-3). In both case, the Beer’s law was obeyed over the rang...
