Devarda Alloy Powder:
Devarda’s alloy is used as reducing agent in analytical chemistry for the determination of nitrates after their reduction to ammonia under alkaline conditions. It owes its name to the Italian chemist Arturo Devarda who synthesized it at the end of the 19th century to develop a new method to analyze nitrate in Chile saltpeter. It was often used in the quantitative or qualitative analysis of nitrates in agriculture and soil science before the development of ion chromatography, the predominant analysis method largely adopted worldwide today.

Devarda Alloy Powder:
Devarda’s alloy is a reducing agent that was commonly used in wet analytical chemistry to produce so-called nascent hydrogen under alkaline conditions in situ. In the Marsh test, used for arsenic determination, hydrogen is generated by contacting zinc powder with hydrochloric acid. So, hydrogen can be conveniently produced at low or high pH, according to the volatily of the species to be detected.

Devarda Alloy Powder:
Devarda’s alloy is an alloy of aluminium, copper and zinc used as a reducing agent in analytical chemistry for the determination of nitrates from a sample after their reduction to ammonia under alkaline conditions, method which has now largely been replaced by ion chromatography.
