- W2094769907 abstract "Abstract La méthode proposée apporte des simplifications au dosage du sélénium dans certaines eaux naturelles. Elk remplace, par une simple evaporation de l'échantillon en milieu HNO3, des procédés fastidieux et délicats de préconcentration, Elk permet le dosage du sélénium à l'étage d'oxydation IV ainsi que du selenium total apres mineralisation de l'échantillon, réaction sélective avec une o-diamine aromatique, et détection du produit de réaction par spectrophotométrie d'absorption atomique sans flamme après ajout d'ions nickel (11). La limite de detection est de 20ng/l. The proposed method for determination of selenium in some natural waters replaces tedious and difficult preconcentration steps by a simple evaporation of the sample in the presence of nitric acid (to minimize loss of selenium). It allows the determination of the element at oxydation level IV as well as the total selenium content after digestion of the sample, selective reaction with an aromatic o-diamine and detection of the reaction product (piazselenol) by electrothermal atomic absorption spectrophotometry after addition of nickel (II). 100ng/l and 200ng/l of selenium can be determined with a relative standard deviation of 14% and 7.3% (respectively: [xbar] = 97.3%, n = 6 and [xbar] = 96.6%, n = 9). The limit of detection is 20ng/l. The native selenium contents of various natural waters were determined and recovery experiments carried out." @default.
