1.
This method is to reduce all of As in poisonous materials to As~(3+)after destroying organism in materials, and then is to transform As~(3+) into arsine in a media of hydrochloric acid and using of boron hydride potassium as a reducing agent.
本方法是将中毒检材进行有机质的破坏,使检材中砷全部还原为三价砷,在盐酸介质中,以硼氢化钾作还原剂,将三价砷转化为砷化氢。

The results showed that As(Ⅲ)was reduced to As efficiently without releasing toxic AsH3 under the condition of current density i=-0.
044 mA/cm2以内时可以很好地将As(Ⅲ)转化为单质砷并抑制砷化氢析出。
补充资料:砷化氢
化学式为AsH3。无色、有蒜味的极毒气体;熔点为-116.3℃,沸点-55℃,密度2.695克/升;分子结构呈棱锥型。砷化氢微溶于水;不稳定,是强还原剂;加热至 300℃时分解。在空气中加热时易燃烧生成砷的氧化物和水,在有限供氧时,生成单质砷和水。砷化氢可在酸性溶液中用金属还原砷化钠、砷化锌、氧化砷制得,也可由砷化铝水解制得。砷化氢中毒能引起呕吐、哆嗦。
