“…For organic salts the method of Rauscher ( 256) is both accurate and rapid. The sample containing 2 to 50 mg. of mercury is reduced by ethanolamine in 5 to 15 minutes and the metallic mercury centrifuged (311) and weighed or dissolved in nitric acid and titrated with thiocyanate. Results are accurate to ±0.2 per cent.…”

“…Unsuccessful attempts were made to replace formaldehyde by a reducing agent such that neither the excess of reagent nor its oxidation product would introduce later complication. The substances tried were acetaldehyde, chloral hydrate, glucose, glycerol (22), and ethanolamine (19,23). As no satisfactory agent was found, it became obvious that the metal must be isolated by filtration.…”
