설명

일반 설명

Potassium cyanide, a potassium salt, is a colorless hygroscopic compound.[1]

애플리케이션

Potassium cyanide has been used:

• in the reduction of cassiterite for Sn isotope analysis[2]
• gold microelectrode fabrication[3]
• to prepare the calibration curve for colorimetric determination of hydrocyanic acid (HCN) levels in Sorghum and Sudangrass species[4]

생화학적/생리학적 작용

Potassium cyanide (KCN) is useful in dyeing, printing, photography, metal cleaning, and manufacturing. It is considered a reversible cytochrome oxidase inhibitor that blocks cellular respiration. KCN is poisonous when inhaled or ingested.[5]
