title: [Study of fundamental parameters of inductively coupled plasma for slurry nebulization--electron density determination].
abstract: 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. There are approximately the same plasma electron density results of 10(15) cm(-3) for the two nebulization ways. The experiment verified that the plasma electron density only shows a litter decrease with 10% TiO2 suspension nebulization into the inductively coupled plasma. This means that the plasma electron density does not change remarkably with high content suspension nebulization into the inductively coupled plasma emission spectrometry instrument. It will help trace elements determination by using high concentration suspension nebulization into the inductively coupled plasma emission spectrometry instrument.
