3 Method summary
3.1 Mercury
The samples were heated acid digestion in acidic medium, mercury is potassium borohydride (sodium) reduction of mercury atoms by a carrier gas (argon) into the atom
Of the vessel. In a special mercury hollow cathode lamp irradiation emits a characteristic wavelength of fluorescence, within a certain range of concentrations, the fluorescence intensity of the mercury-containing
Proportional with standard series to compare quantitatively.
3.2 Arsenic
The sample was heated acid digestion in acidic medium, pentavalent arsenic is reduced thiourea-ascorbic acid into trivalent arsenic, potassium borohydride (sodium) with an acid
And generated a large number of new eco-hydrogen, produce gaseous arsine and trivalent arsenic by a carrier gas (argon) into the atomizer, in a special hollow female arsenic
Extremely light irradiation emits a characteristic wavelength of fluorescence, within a certain range of concentrations, the fluorescence intensity is directly proportional to its arsenic content, compared with standard series
It was quantified.
3.3 Lead
The samples were heated acid digestion in acid medium, lead and potassium borohydride (KBH4) reaction of volatile hydrides by the carrier gas (argon
Gas) into the atomizer, under special illumination lead hollow cathode lamp emits a characteristic wavelength of fluorescence, within a certain range of concentrations, the fluorescence
Intensity proportional to the amount of lead, compared with standard series quantified.
