WebUV-spectrophotometry determination with taurine it’s UV spectra cover those of taurine in analytical zone from 190 to 400 nm (fig. 2, (1)). Due to this authors take advantage to the fact that taurine reacts selectively with ninhydrin after warming. The product of reaction is a color compound and it Despite the different stoichiometry in these mixtures which varies the concentration of the reagent, they all follow the same idea of adding HgO to distilled water and concentrated sulfuric acid. The Denigés' reagent is ultimately mercury(II) sulfate in an aqueous solution. • 5 grams of mercury(II) oxide (HgO) is dissolved in 40 mL of distilled water. The mixture is slowly stirred, while 20 mL of concentrated sulfuric acid is added. After adding another 40 mL of distille…
