Abstract:
(EN) Provided are a platinum oxide colloidal solution with a low impurity content, a method for producing the same, and a platinum oxide colloidal solution injector device. The platinum oxide colloidal solution comprises a platinum oxide or colloidal particles of a platinum oxide dispersed therein, wherein the colloidal particles have a particle size in the range of 1.0 to 4.5 nm and a pH of at least 3.8 and less than 7.8. The method for producing the same includes replacing cations contained in an aqueous solution of hexahydroxoplatinate with hydrogen ions to obtain a suspension of hexahydroxoplatinic acid, adding a pH adjuster to the suspension to adjust the pH of the suspension, irradiating the pH-adjusted suspension with gamma rays to obtain a colloidal solution of the platinum oxide, and replacing cations contained in the colloidal solution with hydrogen ions. The platinum oxide colloidal solution injector device includes a storage unit for storing the platinum oxide colloidal solution, an ion exchanging unit having a hydrogen ion type cation-exchange resin, and a pump.
(FR) L'invention concerne une solution colloïdale d'oxyde de platine ayant une faible teneur en impuretés, sa méthode de production et un dispositif d'injection de solution colloïdale d'oxyde de platine. La solution colloïdale d'oxyde de platine comprend un oxyde de platine ou des particules colloïdales d'un oxyde de platine dispersées dans celle-ci, les particules colloïdales ayant une taille de particule dans la plage de 1,0 à 4,5 nm et un pH d'au moins 3,8 et inférieur à 7,8. La méthode de production de celle-ci comprend le remplacement de cations contenus dans une solution aqueuse d'hexahydroxoplatinate par des ions hydrogène pour obtenir une suspension d'acide hexahydroxoplatinique, l'ajout d'un ajusteur de pH à la suspension pour ajuster le pH de la suspension, l'irradiation de la suspension ajustée en pH avec des rayons gamma pour obtenir une solution colloïdale de l'oxyde de platine, et le remplacement des cations contenus dans la solution colloïdale par des ions hydrogène. Le dispositif d'injection de solution colloïdale d'oxyde de platine comprend une unité de stockage pour stocker la solution colloïdale d'oxyde de platine, une unité d'échange d'ions ayant une résine échangeuse de cations de type ion hydrogène, et une pompe.
(JA) 不純物の含有量が少ない白金酸化物コロイド溶液、その製造方法、及び、白金酸化物コロイド溶液の注入装置を提供する。 白金酸化物コロイド溶液は、白金酸化物又は白金水酸化物のコロイド粒子が分散しており、コロイド粒子の粒径が1.0nm以上4.5nm以下の範囲であり、pHが3.8以上7.8未満である。その製造方法は、ヘキサヒドロキソ白金酸塩の水溶液に含まれる陽イオンを水素イオンに置換してヘキサヒドロキソ白金酸の懸濁液とし、懸濁液にpH調整剤を添加して懸濁液のpHを調整し、pHを調整した懸濁液にガンマ線を照射して白金酸化物のコロイド溶液とし、コロイド溶液に含まれる陽イオンを水素イオンに置換する。白金酸化物コロイド溶液の注入装置は、白金酸化物コロイド溶液を貯蔵する貯蔵部と、水素イオン型陽イオン交換樹脂を有するイオン交換部と、ポンプと、を備える。
