Abstract
Procédé de séparation de corrinoides par adsorption sélective et/ou élution sélective au moyen d'un adsorbant polymérique ayant une grande surface spécifique, dans lequel a)on lie les corrinoides complets sur l'adsorbant à partir d'une solution aqueuse ou d'un mélange solvant aqueux contenant au plus 20 % en volume d'un alcool aliphatique inférieur miscible à l'eau ou au plus 5 % en volume d'une cétone aliphatique inférieure miscible à l'eau, dont le pH a été ajusté à 8 à 11, b) on élue les corrinoides incomplets à partir des corrinoides adsorbés sur l'adsorbant de façon connue, avec une solution aqueuse ou un mélange solvant aqueux contenant au plus 20 % en volume d'un alcool aliphatique inférieur miscible à l'eau ou au plus 5% en volume d'une cétone aliphatique inférieure miscible à l'eau, dont le pH a été ajusté à 8 à 11.
