Abstract

Abstract

The influence to the interferences on determination of Sb using five kinds of graphite tubes is reported. The introduction of microtube or platform, for its more homogeneous temperature, can increase the sensitivity and inhibits the interferences of foreign ions. The interference of nicle, which can not be eliminated with tube-in-tube technique, can be eliminated by the addition of EDTA; coating of Mo and W carbides and measurement of peak area.
