摘　　要：用活性炭吸附方法对PH3进行脱除净化,主要考查了氧含量、浸渍液浓度、温度对吸附效率的影响,在氧含量1.5%,浸渍液HCl浓度为5%,温度为70℃的条件下,在磷化氢进口浓度为1100mgm3时,磷化氢的净化效率保持在90%以上,同时对反应机理进行了分析。Activated carbon adsorption is used to purify PH_3.It is examined the effect of oxygen, liquid of dipping, and reaction temperature on the adsorption efficiency.Under the condtion of 1.5% of oxygen volume, 5% hydrochloric acid dipping and reaction temperature 70℃,90% of PH_3 has been removed when the concentration of PH_3 is 1 100 mg/m3 at inlet, and the mechanism anlysis is conducted.
