方酸类化合物在近红外区强而窄的吸收以及它们对氰化物特有的敏感性使它们成为理想的氰根离子的传感器。
The intense and sharp absorption of squaraines in the near IR and their highly selective decoloration induced by cyanide makes them suitable to serve as cyanide sensors.
但那些英国的饮茶人士还算走运，普鲁士蓝是一种化合物分子，它在人体中几乎没可能释放出氰根离子。所以这种物质最终将安全无害的从人体中排出。
Fortunately for the tea drinkers of Britain, Prussian blue is a complex molecule, so it is almost impossible to release the cyanide ion from it and the poison passes harmlessly through the body.
