罪案剧里常有这样的场景:调查人员来到一处整洁的房间,掏出喷壶撒上些试剂,再遮上光让房间暗下来,然后便是见证奇迹的一刻———原本空白的墙面、地面上出现了或成片或呈斑点的蓝色荧光,于是调查人员酷酷地下了论断:“有隐藏的血迹,这是犯罪现场。”现实生活中真有这种能让看不见的血迹现形的神奇药水吗?答案是肯定的。那就是以“发光氨”的诨号著名,由3-氨基邻苯二甲酰肼(也就是鲁米诺)、过氧化氢以及氢氧化物配制成的鲁米诺试剂。鲁米诺试剂发光的原理其实和我们在演唱会上甩的荧光棒差不多,都是富含能量、处在不稳定激发态的化合物在变成稳定的基态的过程中,能量以光的形式散发出来的缘故。
Crime scene is often the scene: investigators came to a neat room, took out the watering can sprinkle some reagents, and then cover the light to darken the room, and then is the moment to witness the miracle - the original blank wall Face, the ground appeared or into pieces or spots of blue fluorescence, so investigators coolly under the conclusion: “There is hidden blood, it is a crime scene. ” In real life, this can make invisible Is there any magic potion in the blood? The answer is yes. That’s known as the Luminol®, a luminol reagent formulated with 3-aminophthalhydrazide (also known as luminol), hydrogen peroxide, and hydroxide. Luminol’s principle of luminescence is actually similar to the fluorescent rods we throw at the concert. All of them are energy-rich, and the compounds in the unstable excited state emit light in the form of light when they become a stable ground state Out of reason.
