Title
(FR) PROCEDE DE DOSAGE D'UN ELEMENT PRESENT EN TOUT OU PARTIE SOUS LA FORME DE PARTICULES EN SUSPENSION DANS UN LIQUIDE.
Abstract
(FR)
La présente invention concerne un procédé de dosage d'un élément présent en tout ou partie sous la forme de particules en suspension dans un liquide, comprenant au moins les étapes consistant en : (i) disposer d'un échantillon de ladite suspension à analyser, supplémenté avec au moins un agent anti-radicaux libres hydrocarboné ; (ii) soumettre ledit échantillon (i) à une sonication, dans des conditions non réactives à l'égard des particules dudit élément à doser ; (iii) doser ledit élément par analyse spectrométrique de l'échantillon (ii) ; l'étape (iii) étant réalisée consécutivement ou simultanément à l'étape (ii) de sonication.
