Moderation: Hans Günther Schmalz

Phosphorus was discovered in 1669 as the 13th element by the German alchemist Hennig Brand in Hamburg. Phosphorus is extracted from phosphate rock. Phosphorus is essential for life. The recovery of phosphorus from wastewater and sewage sludge is essential for this essential element because the resource is finite. Phosphorus also has a dark side. It was used in wartime in incendiary bombs and Molotov cocktails, and there are also known cases of murder by poisoning with white phosphorus. This is why phosphorus is sometimes referred to as the "devil's element". The chemistry of phosphorus is one of the most fascinating areas of inorganic and organic chemistry. It encompasses an enormous number of compound classes.
