time intervals at a fixed temperature of 80 After sonication for different time intervals, the resulted extracted solution were centrifuged at 3000 rpm for 5 min, and supernatant liquids were collected in a polyethylene flask for the determinations of Hg by CVAAS.
Before 1970, U-Hg was analyzed using the dithizone method, and afterward using the above-mentioned CVAAS technique expressed in micrograms per liter.
In CVAAS the sample, whether in solid, liquid or gas form, is first placed into a solution, then introduced into the atomic absorption spectrometer where it is struck by a hollow cathode lamp emitting a wavelength specific to mercury (when using the system as a mercury analyzer).
As stated before, the healthiest sales of mercury analyzers are made by manufacturers of stand-alone CVAAS systems.
