Título: Reaction of gallium arsenide with concentrated acids : formation of arsine / Nelson Scott, Dean E. Carter and Quintus FernandoAutor: Scott, Nelson
Notas: Sumario: Crystalline particles of gallium arsenide (GaAs) (-2 microm in diameter) react with concentrated hydrochloride acid (HCL) (11.6 to 9M) to form highly toxic arsine (AsH3) gas. A spectrophotometric method, based on the reaction of AsH3 with silver diethyldithiocarbamate in a chloroform solution containing morpholine was used to detect AsH3 gas dissolved in aqueous solutions and to determine the AsH3 gas that was liberated by the reaction of GaAs with HClRegistros relacionados: En: American Industrial Hygiene Association journal. - Akron, Ohio. - Vol. 50, nº 7, July 1989 ; p. 379-381Materia / lugar / evento: Higiene industrial Contaminantes químicos Arsénico Arseniuro de galio Ácido clorhídrico Reacciones químicas Toxicidad Otros autores: Carter, Dean E.
