Abstract

Linvention concerne une composition pour le traitement de lentartrage et de la formation de dépôts causés par des matières radioactives naturelles, ladite composition comprenant un ou plusieurs agents d'extraction qui attirent idéalement les isotopes radioactifs sur dautres formes de cations alcalino-terreux. Linvention concerne également une composition qui forme un liant polydentelé avec un ou plusieurs métaux pour quils agissent comme transporteurs pour les éléments radioactifs. La composition comprend des composants qui améliorent la stabilisation de la complexation de la coordination des isotopes radioactifs pendant la formation des liants polydentelés.
