Determination of iron in injected suspensions and organs: Le dosage du fer contenu dans les suspensions de MIL-88A et MIL-88Bt injectes aux animaux est effectu par spectrophotomtrie UV-Visible la longueur d'onde de 520 nm, par colorimtrie spcifique des ions ferreux avec la bipyridine (formation d'un complexe rouge), aprs solubilisation de l'oxyde de fer dans de l'acide sulfurique concentr, et rduction des ions ferriques en ions ferreux par l'acide ascorbique.The determination of the iron contained in the suspensions of MIL-88A and MIL-88Bt injected into the animals is carried out by UV-Vis spectrophotometry at the wavelength of 520 nm, by specific colorimetry of the ferrous ions with the bipyridine (formation of a red complex), after solubilization of iron oxide in concentrated sulfuric acid, and reduction of ferric ions to ferrous ions by ascorbic acid
