Methods for Separating Mixtures | Chemistry for Non-Majors

Filtration. Filtration is a separation method used to separate out pure substances in mixtures comprised of particles some of which are large enough in size to be captured with a porous material.Particle size can vary considerably, given the type of mixture. For instance, stream water is a mixture that contains naturally occurring biological organisms like bacteria, viruses, and protozoans.

Rubidium azide - Wikipedia

Rubidium azide has a high pressure structure transition, which occurs at about 4.8 kilobars of pressure at 0 °C. The transition boundary of the II/III transition can be defined by the relationship P = 4.82 + 0.0240 t {displaystyle P=4.82+0.0240t}, where P {displaystyle P} is the pressure in kilobars and t {displaystyle t} is the ...

Rubidium 82 | Article about rubidium 82 by The Free Dictionary

Rubidium salts are used in glasses and ceramics. Rubidium-87, a radioactive isotope (half-life about 5 × 10 11 years), makes up about 28% of natural rubidium; the balance is the stable isotope rubidium-85. Fifteen other isotopes are known. Rubidium was discovered with cesium in 1861 by R. W. Bunsen Bunsen, Robert Wilhelm

cesium | Description, Symbol, Uses, & Facts | Britannica

The primary difficulty associated with the production of pure cesium is that cesium is always found together with rubidium in nature and is also mixed with other alkali metals. Because cesium and rubidium are very similar chemically, their separation presented numerous problems before the advent of ion-exchange methods and ion-specific complexing agents such as crown ethers.
