Determination of Organomercurial by Spectroscopic method

บทคัดย่อ

The concentration of six-substituted benzylmercuric chlorides was measured spectrophotometrically with an Ultraviolet (UV) Cary-15 Spectrophotometer. The of the organomercurial were found at wavelength between 245-255 nm with extinction coefficient (E) of 14000-19000 M cm. The extinction coefficient of each compound was determined with know concentration (10 m.) in a 1 cm cell. To quantitatively measure benzylmercuric chloride and its derivatives, known amount at various concentrations were prepared to serve as experimental samples. The uv spectrophotometer shows practical performance to determine trace amount of mercury at very low concentration as 10 m of organomercurial and the experimental error about two percents was noticed.
