“…Les mtthodes de determination analytique du thorium dans les minerais et les produits mttallurgiques thoriferes sont assez nombreuses et leur choix dtpend de multiples facteurs tels que la prtcision dtsirte, l'importance de la teneur, la nature et l'importance des autres tltments, la rapiditt tventuellement exigte, le prix des appareillages ntcessaires (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16). Les proctdts les plus courallts sont la gravimttrie par l'iodate ou par le thiosulfate (I, ll), la titrimttrie par le molybdate ou l'oxinate, la colorimttrie par l'acide arsCnophCnylazonaphtol-disulfonique (2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12), la fluorimttrie par l'amino-hydroxyanthraquinone (12), la spectrophotomttrie par l'acide dimtthyl aminophtnylarsinique (2,4), la fluorescence, la polarographie et l'analyse spectrale (1, 7, 1 l), la complexomttrie (8,9), l'tchange ionique et l'extraction liquide-liquide (13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23).…”
