A process is described for reducing the acid content of a solution comprising a hydroxylamine salt and an acid. In one embodiment, the process comprises the steps of: (A) providing an electrolysis cell comprising an anolyte compartment containing an anode, a catholyte compartment containing a cathode, said compartments being separated from each other by an anionic membrane; (B) providing an aqueous solution comprising an acid and water in the anolyte compartment, and an aqueous solution comprising the hydroxylamine, the acid and water in the catholyte compartment; (C) passing a direct current through the electrolysis cell for a period of time effective to reduce the acid content in the catholyte compartment; and (D) recovering a hydroxylamine salt solution from the catholyte compartment containing a reduced amount of acid. The process of the present invention results in the recovery of hydroxylamine salt solutions containing significantly reduced amounts of acid.
