Abstract : Three methods for extraction of metal ions from the matrix of asbestos and mica were investigated. These were treatment with the chelating agent, 8-hydroxyquinoline, leaching with concentrated HCl, and leaching with 10% aqueous NaOH. Some success was achieved with asbestos treatments. Attempts to increase the molecular weights of the polymer derived from the reaction of an organohalosilane and Na silicates were only partially successful. Methods involving time and temperature effects; the use of a crosslinking agent, methyltrichlorosilane; and refluxing with catalytic quantities of KOH were only moderately successful. Polymers containing phen l groups having characteristics similar to those obtained from dimethyldichlorosilane and Na2Si 3 have not yet been prepared. (Author)
