The permeability of CH_3Br and the waste gas pollution control
Chen Yuansheng;Xie Yulin;Shanghai Museum;
In this paper the permeability of various films has been studied.The simple fumigating chamber which is made of the selected complex film prevents the leakage of methyl-bromide validly.The activated carbon used as an absorbent and the multistage absorption towers guarantee the treated relief gas to reach a standard level of environmental hygiene of1 mg/m~3.The improved gas chromatographic technique makes the detectability reach to 0.1 mg/m~3 and it can be used as a method to analyse the trace of CH_3 Br which remains in the fumigated materials.The remainder of CH_3 Br can be desorbed by the activated carbon throughly in one week.
