3 Method summary

In acidic medium, the test solution and lead to pre-oxidant ferricyanide, cadmium first and sensitizer Co2 and thiourea, arsenic, and antimony first pre-reduction L- cysteine effect agent, and then with sodium borohydride to form the corresponding volatile components, respectively, by the carrier gas into the quartz electrothermal atomizer The atomization, the corresponding element in a special hollow cathode lamp irradiation, the corresponding ground state atoms are excited to high energy state, the deactivation to the ground state, the hair Characteristic wavelength emitted fluorescence, the fluorescence intensity is proportional to the corresponding elements in the element corresponding quantitative comparison with standard series.

4 Reagents and materials

Unless otherwise specified, reagents were pure class distinctions in the analysis used in the test water should be consistent with a water GB/T 6682 stipulated. 4.1 Glacial acetic acid (ρ = 1.05g/mL). 4.2 4% (mass concentration) acetic acid solution. Weigh 40g (accurate to 0.1g) in glacial acetic acid (4.1) in 1L flask with water to volume, Mix well. 4.3 hydrochloric acid (ρ = 1.19g/mL). 4.4 hydrochloric acid (199). HCl (4.3) 10mL, diluted with water to 1000mL. This solution is used for the determination of arsenic and antimony. 4.5 hydrochloric acid (298). HCl (4.3) 20mL, diluted with water to 1000mL. This solution is used for determination of cadmium. ......
