Abstract

Rubidium is a valuable element due to its cost and in terms of application areas. For this reason, the studies made on the element rubidium is still quite attractive. There is no Rubidiums own mineral deposits. Rb, is obtained as a minor side from lepidolite and pollucitin process. These deposits are located around the world together in a few pegmatite zones. In this study, the element of rubidium and studies about the separation of the rubidium investigated and given. For separation of the rubidium precipitation method, extraction and absorption methods are used. These methods has studied with different rock samples and mixtures of alkali chloride. Rubidium, as a compound of Rb2SnCl6 separated by precipitation. The new methods are used for the separation of Rubidium is extraction of the element by the crown ethers. Although method is expensive %100 rubidium is obtained with this method. © Afyon Kocatepe Üniversitesi

Rubidyumun Çeşitli Kayaçlardan ve Alkali Klorür Karışımlarından Ayrılması Amacıyla Yapılan Çalışmalar

Abstract

Rubidyum hem maddi hemde kullanım alanları açısından oldukça değerli bir elementtir. Bu nedenle rubidyum elementiyle ilgili yapılan çalışmalar oldukça çekici hala gelmektedir. Rubidyumun kendisine ait mineral yatakları yoktur. Rb, lepidolit ve pollucitin prosesinin yan minörü olarak elde edilir. Bu yataklar dünyada birkaç pegmatit bölgeleri içinde birlikte bulunur. Bu çalışmada rubidyum elementi ve bugüne kadar rubidyum elementinin ayrılması amacıyla yapılmış çalışmalar araştırılmış ve yer verilmiştir. Rubidyumun ayrılması için, çöktürme yöntemi, ekstraksiyon ve absorbsiyon yöntemleri kullanılmıştır. Bu yöntemler farklı kaya örneklerinde ve alkali klorür karışımlarında çalışılmıştır. Çöktürme yöntemlerinde rubidyum RbSnCl6 bileşiği halinde çöktürülerek ayrılmıştır. Rubidyumun ayrılması amacıyla kullanılan en yeni metotlar rubidyumun taç eterlerle ektraksiyonuna dayanır. Bu yöntem pahalı olmasına rağmen % 100 verimle rubidyum elde edilmektedir
