Title (EN) MEDICAL YTTRIUM PHOSPHATE CARBON MICROSPHERE AND PREPARATION METHOD THEREFOR
(FR) MICROSPHÈRE DE PHOSPHATE D'YTTRIUM À USAGE MÉDICAL ET SON PROCÉDÉ DE PRÉPARATION
(ZH) 医用磷酸钇碳微球及其制备方法
Abstract:
(EN) A medical yttrium phosphate carbon microsphere for use in tumor treatment and a preparation method therefor. A medical yttrium phosphate carbon microsphere for use in tumor treatment and a preparation method therefor. The medical yttrium phosphate [90Y32PO4] carbon microsphere is prepared with a carbon microsphere being used to adsorb an yttrium tartrate-90 (90Y-tartaric acid) complex produced by reacting 90YCl3 with tartaric acid, then processed with an Na3 32PO4 solution to produce 90Y32PO4 that is then precipitated, solidified, and purified.
(FR) L'invention concerne une microsphère de phosphate d'yttrium à usage médical et son procédé de préparation. Cette microsphère de phosphate d'yttrium à usage médical [ 90Y 32PO 4] est obtenue par adsorption de microsphère 90YCl 3 que l'on fait réagir avec un complexe d'yttrium d'acide tartrique de 90Y (90Y-acide tartrique) mélangé à une solution Na 3 32PO 4 de manière à obtenir par précipitation et durcissement une préparation purifiée.
(ZH) 一种用于肿瘤治疗的医用磷酸钇碳微球及其制备方法。该医用磷酸钇[ 90Y 32PO 4]碳微球是用碳微球吸附 90YCl 3与酒石酸溶液反应生成的酒石酸钇-90( 90Y-酒石酸)络合物,再经Na 3 32PO 4溶液处理生成 90Y 32PO 4沉淀固化及净化处理制备而成的。
