[Study of fundamental parameters of inductively coupled plasma for slurry nebulization--electron density determination].

The electron density of the plasma for slurry nebulization inductively coupled plasma emission spectrometry was determined and reported in the present paper. The Stark broadening method of Hg line (486.1 nm) was chosen and used to determine the electron density of the plasma for nebulization into the inductively coupled plasma with both the aqueous solution and different concentration titanium slurry.

[Study of fundamental parameters of inductively coupled plasma with slurry nebulization--I. Excitation temperature determination].

The excitation temperature of plasma with slurry nebulization into inductively coupled plasma emission spectrometry was determined and reported in the present paper. Ti-lines and multi spectrum lines method were chosen and used to determine the excitation temperature with nebulization into the inductively coupled plasma with both aqueous solution and 0.05% titanium slurry.

[Research advance in slurry sample introduction for plasma emission spectrometry/mass spectrometry].

The present review is focused on the advances and applications of slurry introduction for plasma spectrometry/mass spectrometry. Preparation and characterization of the suspensions are described, including the methods for decreasing the particle size such as the bottle and bead method, mixing mill method, vibration mill method, and supersonic mill method. Dispersion of the particles can be controlled via adding dispersant and pH adjustment.

[Direct determination of Nb in titanium oxide using slurry sample introduction by axial viewing inductively coupled plasma optical emission spectrometry].

By using dispersant polyacrylate amine (NH4PAA) to disperse TiO2, effects of different dispersants, pH value and the amount of dispersant on TiO2 slurry were investigated. The pH value of the medium and the dispersant amount were optimized, and a stable and homogeneous suspension was prepared. Nb in TiO2 was determined by an axial viewing ICP-OES spectrometer.
