Promoted reaction of hydrogen gas generation and deformed morphology of chrysotile in aqueous solutions under irradiation

Aoyagi, Noboru ; Nagaishi, Ryuji ; Esaka, Fumitaka ; Yamada, Reiji

Interfacial reaction on chrysotile in acidic aqueous solutions which ispromoted by irradiation of $^{60}$ Co -ray or electron beam was studied by analyzing the production of hydrogen gas and morphological alteration of fibril structure. The amount of generated hydrogen gas was proportional to the dose of irradiation and larger than the other particles such as alumina or silica known as a reactive surface donor for radicals. An expedited reaction in which chrysotile fibrous structure fell apart and come into particles was found more in SEM-EDX measurementwith increasing the concentrations of sulfuric acid as 0.2M, 0.4M, 0.8M and 2.0M.
