Of the two predominant forms of arsenic in water, arsenate and arsenite, most treatment processes are effective at removing arsenate, but not arsenite, since arsenite is typically non-charged below pH 9.2. Therefore, treatment for the removal of arsenic often includes an oxidation step to convert ar ...

Marie Lafarge
Marie-Fortunée Lafarge (née Capelle; 15 January 1816 – 7 November 1852) was a Frenchwoman who was convicted of murdering her husband by arsenic poisoning in 1840. Her case became notable, because it was one of the first trials to be followed by the public through daily newspaper reports, and because she was the first person convicted largely on direct forensic toxicological evidence. However, questions about her guilt had divided French society to the extent that it is often compared to the better-known Dreyfus affair.
