説明

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