Methods have been developed to quantify phosphorus in vitro adsorption on inhalable CeO 2 particles. Two assays are potentially useful: adsorption measurement of 32P and X-ray spectrometry.

Des méthodes in vitro pour quantifier l'adsorption du phosphore sur des particules inhalables de CeO 2 ont été développées. Deux tests s'avèrent utilisables : la mesure de l'adsorption du 32P et la spectrométrie X.

Key words: dissolution -- phosphate -- oxyde de cérium -- spectrométrie X
