Abstract:
(EN) The present invention provides a method for removing divalent metallic cations from a macromolecular compound having an anionic functional group and containing a divalent metallic cation, the method comprising: (1) suspending a macromolecular compound having an anionic functional group and containing a divalent metallic cation in a solution in which an electrolyte capable of releasing an alkali metallic ion is dissolved at a concentration that causes the macromolecular compound to salt out, and (2) carrying out an ion-exchange reaction on the resultant suspension so as to exchange divalent metallic cations contained in the macromolecular compound for said alkali metal ion.
(FR) La présente invention concerne un procédé d'élimination de cations métalliques divalents à partir d'un composé macromoléculaire ayant un groupe fonctionnel anionique et contenant un cation métallique divalent, le procédé comprenant : (1) la mise en suspension d'un composé macromoléculaire ayant un groupe fonctionnel anionique et contenant un cation métallique divalent dans une solution dans laquelle un électrolyte capable de libérer un ion métallique alcalin est dissous à une concentration qui provoque l'extraction du composé macromoléculaire, et (2) la mise en œuvre d'une réaction d'échange d'ions sur la suspension résultante de manière à échanger des cations métalliques divalents contenus dans le composé macromoléculaire pour ledit ion de métal alcalin.
(JA) 本発明は、2価金属カチオンを含有するアニオン性官能基を有する高分子化合物から、2価金属カチオンを除去する方法であって、(1)2価金属カチオンを含有するアニオン性官能基を有する高分子化合物を、アルカリ金属イオンを放出する電解質を該高分子化合物を塩析させる濃度で溶解した溶液中に懸濁すること、及び(2)得られた懸濁液中で、該高分子化合物に含有される2価金属カチオンを、該アルカリ金属イオンに交換するイオン交換反応を行うことを含む、方法を提供する。
