A process for the destruction of NO x in sulphuric acid is provided which preferably comprises the addition of a reducing agent, such as sulfamic acid, to the product acid, followed by the addition of an oxidizing agent such as hydrogen peroxide. The process allows for the relatively rapid removal of NO x under typically encountered plant conditions, while minimizing the excess use of NO x-removing chemicals. A lower cost, safer method for NO x removal is achieved.
