Abstract

Bismuth subnitrate 5 (BiO.NO3).BiO.OH.4H2O is prepared by electrolysing an aqueous solution of an inorganic nitrate, e.g. 10-40% by weight of an alkali metal or ammonium nitrate, maintained at a pH in the range 1 to 7 by adding HNO3 using a Bi anode and recovering the subnitrate deposited at the anode; the cathode may be of stainless steel. The process may be operated continuously, the subnitrate precipitated from the anode being withdrawn in a stream of electrolyte from the electrolysis vessel, and after filtering recycling the electrolyte, regenerated and heated if necessary, to the vessel. A prior process is disclosed using an electrolytic cell having a Bi anode, Ni cathode, and separate NaNO3 anolyte and NaOH catholyte, wherein bismuthyl nitrate is electrolytically formed.
