The article presents an effective method for determining trace amounts of arsine in gases by its concentration in a fluidized bed of silica gel treated with silver nitrate, in the form arsenite silver and subsequent recovery present it in an acid medium with zinc absorption produced during this arsine solution diethylditiokarbaminate painted silver and photometry solution. The possibility of application of the method is practically tested using the commercial propylene, for the determination of arsine in various gaseous systems.
