A simple and rapid procedure for the isolation and determination of free ferricyanide and ferrocyanide in sodium nitroferricyanide (nitroprusside) was developed. The method, employing aluminum oxide column chromatography, was sensitive enough to detect ferricyanide and ferrocyanide at the 0.05% level.
开发了一种简单快速的方法,用于分离和测定硝普钠中的游离铁氰化物和亚铁氰化物。该方法采用氧化铝柱色谱法,灵敏度足以检测出含量为0.05%的铁氰化物和亚铁氰化物。
