Chemiluminescence - Luminol Still Images A buffered luminol solution with a copper(II) catalyst is added to the funnel on the left. A hydrogen peroxide solution is added to the funnel on the right. On releasing the rubber tubing the solutions mix. The chemical reaction generates energy which is seen as blue light. This process is chemiluminescence. When the reacting solution mixes with a dye, fluorescein, the light energy from the reaction causes the fluorescein to give off a greenish light in a process called fluorescence. You can get at large JPEG versions of the images by means of the following links. 0 1 2 3 4 5 6 7 8 Back to the topic
