14 SEPARATION TECHNIQUES

14 SEPARATION TECHNIQUES 141 Introduction The methods for separating, collecting, and detecting radionuclides are similar to ordinary analytical procedures and employ many of the chemical and physical principles that apply to their nonradioactive isotopes However, some important aspects of the behavior of radionuclides areMany researchers have used various mechanical methods to separate metals and nonmetals from waste printed circuits boards such as multicrushing, grinding, electrostatic separation, gravity separation, density based separation and magnetic separation 34 Source: Li JingYing et al 2012 Adsorption This is the most costefficient and effective (PDF) " PLATINUM EXTRACTION AND PURIFICATION, Platinum is a transition metal in Group 10 (VIIIB) of the periodic table The periodic table is a chart that shows how chemical elements are related to each other Platinum is also a member of a group of metals named after itself Other platinum metals include ruthenium, rhodium, palladium, osmium, and indiumPlatinum, Chemical Element reaction, water, uses

The Properties and Applications of Platinum

Platinum is a dense, stable and rare metal that is often used in jewelry for its attractive, silverlike appearance, as well as in medical, electronic, and chemical applications due to its various and unique chemical and physical properties The recovery of platinum group metals (PGMs) from spent automobile catalysts is a difficult process because of their relatively low contents in the scrap In this study, to improve the efficiency of the existing recycling techniques, a novel physical concentration method involving treatment with FeCl2 vapor has been examined The reactions occurring between typical catalyst components and Recovery of Platinum Group Metals from Spent Catalysts A centrifuge was the first device to separate chemical isotopes, used by Jesse Beams of the University of Virginia to separate chlorine35 from chlorine37 in 1934 In 1940, American physicists thought that the centrifuge was the best possibility for largescale enrichment, and Beams received government money to attempt uranium enrichment via Isotope Separation Methods Atomic Heritage Foundation
