- 摘要：
- A simple analytical method was established for simultaneous multielement determination of As, Se and Sb in river water with GF-AAS using a TiO2 slurry sampling. Titanium dioxide (TiO2, -0.5 μm) was applied as a sorbent to separate and concentrate these elements in sample solution (100-300 ml); after filtration, slurry was prepared with the solid phase and 5.0 ml ultrapure water. In order to apply for river-water samples, effect of TiO2 in atomization, effect of organic species of their metal and interference of foreign ions were investigated. The proposed method was applied to JSAC 0302 and river water.
