| Abstract: | Determination of selenium in water and wastewater by GFAAS, taking Ni compound as matrix improvement reagent, it could increase ashing and atomisation temperature and remove interference of the matrix,The detection limit of this method was 1.4ppb. The CV% of wastewater determination was 2.9-7.5%,and the rate of spike recovery was 95.0-105.4%. |
