Title
(EN) AMMONIA ADSORPTION ENTRAINED POLYMER
(FR) POLYMÈRE ENTRAÎNÉ PAR ADSORPTION D'AMMONIAC
Abstract
(EN) Disclosed are entrained polymer compositions configured to absorb ammonia. Also disclosed is a method of retaining an ammonia/ammonium chloride buffer solution. The method includes the step of placing the ammonia/ammonium chloride buffer solution in a vessel, which contains a desiccant entrained polymer material not in direct contact with the ammonia/ ammonium chloride buffer solution. The desiccant entrained polymer material is made of a base polymer, a desiccant, and a channeling agent. The invented method maintains the properties of the buffer solution by regulating the amount of ammonia and/or moisture absorption by the desiccant entrained polymer.
(FR) L'invention concerne des compositions polymères entraînées configurées pour absorber l'ammoniac. L'invention concerne également un procédé de retenue d'une solution tampon d'ammoniac/chlorure d'ammonium. Le procédé comprend l'étape consistant à placer la solution tampon d'ammoniac/chlorure d'ammonium dans un récipient, qui contient un matériau polymère entraîné par un déshydratant qui n'est pas en contact direct avec la solution tampon d'ammoniac/chlorure d'ammonium. Le matériau polymère entraîné par déshydratant est constitué d'un polymère de base, d'un déshydratant et d'un agent de canalisation. Le procédé de l'invention maintient les propriétés de la solution tampon par régulation de la quantité d'ammoniac et/ou d'absorption d'humidité par le polymère entraîné par déshydratant.
