砷制备
1.由三氧化二砷跟碳反应制得。气相还原法将备有气化段、反应段、析出段的三个电炉的装置组装起来。中央反应部分是内径为20～25mm的石英管，在其中装入经真空加热排掉气体的木炭，两端用石英棉堵住，在石英盘里放人三氧化二砷，放到气化段，以400～500 mI/min的速度通人经提纯的氮气。将气化段保持在400℃，反应段650℃，析出段350～400℃，经反应约1h，析出单质砷，再经蒸馏，制得砷成品。
2.用胂(AsH3)制备在制备胂的过程中所混入的杂质为其他氢化物即硫化氢H2S、硒化氢H2Se、锑化氢SbH3等。精制时，可先用液氮冷却进行液化分馏，再用氢氧化钾水溶液洗涤，最后通过CaCl2、γ-Al2O3、P2O5等。所得到的精制胂在加热至600℃以上的石英管里热分解，可以得到高纯度砷，纯度在99.999%以上。AsH3在280℃以上几乎是100%热分解，为使分解完全，在石英管的加热层中，最好能填充石英制拉西环等填料。
