Under appropriate conditions, both surface areas and cation exchange capacities of clay minerals can be measured by absorption of methylene blue from aqueous solutions. The method has been applied to two kaolinites, one illite, and one montmorillonite, all initially saturated with Na+ ions. For Na-montmorillonite, the total area, internal plus external, is measured. For Ca-montmorillonite, entry of methylene blue molecules appears to be restricted by the much smaller expansion of the Ca- clay in water. X-ray diffraction data clarify the absorption behavior in Na- and Ca-montmorillonite, and in particular it is shown that two orientations of the methylene blue molecules are involved.

Résumé

Résumé

Dans les conditions appropriées, la superficie et la capacité d’échange de cations des minéraux argileux peuvent étre mesurés par absorption du bleu de méthylène des solutions aqueuses. La méthode a été appliquée à deux kaolins, une illite, et une montmorillonite, tous ayant été préalablement saturés d’ions Na+. Pour la montmorillonite-Na, la superficie totale, interne et externe, a été mesurée. Dans le cas de montmorillonite-Ca, l’entrée des molécules du bleu de méthylène semble être restrainte par la dilatation bien plus petite de l’argile-Ca dans de l’eau. Les données de la diffraction des rayons X expliquent le phénomène d’absorption dans montmorillonite-Na et -Ca et on voit, en particulier, qu’il existe deux orientations des molécules du bleu de méthylène.

Kurzreferat

Kurzreferat

Unter geeigneten Bedingungen können sowohl Flächeninhalte als auch Kationenaustauschvermögen von Tonmineralen durch Absorption von Methylenblau aus wässrigen Lösungen gemessen werden. Die Methode wurde auf zwei Kaolinite, einen Illit und einen Montmorillonit, die alle ursprünglich mit Na+ Ionen gesättigt waren, angewendet. Für Na-Montmorillonit wird die Gesamtfläche, innen sowie aussen, gemessen. Für Ca-Montmorillonit scheint der Eintritt der Methylenblaumoleküle dutch die viel geringere Ausdehnung des Ca-Tons in Wasser begrenzt zu sein. Das Absorptionsverhalten in Na- und Ca-Montmorillonit wird durch Röntgenbeugungsdaten klargelegt, und insbesonders wird gezeigt, dass zwei Orientierungen der Methylenblaumoleküle beteiligt sind.

Резюме

Резюме

Поглощение глинистыми минералами метиленового голубого из водных растворов при благоприятных условиях может быть использовано для измерения как площади поверхности, так и катионо-обменной емкости. Предложенная методика была применена для исследования двух каолинитов, одного иллита и одного монтмориллонита; все образцы первоначально насыщались ионами Nа+. Для Ка-монтмориллонита определена общая (внутренняя и внешняя) поверхность. У Са-монтмориллонита внедрение молекул метиленового голубого, по-видимому, вызывает меньшее разбухание в воде. Рентгеновские данные позволили объяснить агсорбционные свойства Na- и Са-монтмориллонитов и в частности указали на две ориентировки метиленового голубого.
