liminol 係咩黎?Do you mean luminol (C8H7O3N3)??
It is a powder, when mix with H2O2, it will create a strong glow, But it needs a catalyst, i think that is why you need Cu(ii) ions to be the catalyst.


我可以響咩 chemical 裡面搵到?
I think you can buy it in chemical stores. There is one in Prince Edward.

Precautions:
According to the latest MSDS information, luminol is considered an irritant and may cause redness and watering of the eyes. Sodium perborate and sodium carbonate (two components of one luminol preparation) are also irritants to mucous membranes. I personally find the preparation by Weber (1966) less irritating to the eyes. This formulation can be found in the textbook, Interpretation of Bloodstain Evidence at Crime Scenes, edited by Stuart James and William Eckert.
I recommend a mist type filter mask, eye goggles and latex gloves. A respirator with mist cartridges may be useful if you plan to spray a lot of luminol.

If you wear contacts, take them out and use glasses! I again, also recommend the luminol preparation by Weber as it uses much less concentrated ingredients and I feel it's not as harmful.
