Book Description

Excerpt from The Scientific Transactions of the Royal Dublin Society, 1898-1902, Vol. 7 We were under the necessity of obtaining a specimen of pure iron for the purpose of obtaining a spectrum of this metal perfectly free from gallium, manganese, and one or two other elements, such as chromium, with which it is usually associated. For this purpose we made use of the iron in a pulverulent form, which is separated from potassium ferrocyanide when this substance is fused with potassium carbonate, and the black powder is separated from the potassium cyanide by solution in water or alcohol, and afterwards washed and dried. We believe this to be the purest form of iron which has yet been made. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
