This method describes the collection and analysis of airborne acids using Ion Chromatography. The method measures the total concentration of four airborne anions. The corresponding acids may be collected on a single sampler and determined simultaneously. Hydrogen bromide is used in the manufacture of organic and inorganic bromides and hydrobromic acid, as a reducing agent, and as a catalyst in controlled oxidations. HBr is also used in the alkylation of aromatic compounds, and in the isomerization of conjugated diolefins.
Most nitric acid is used in fertilizer as ammonium nitrate and in the manufacture of explosives.
Nitric acid is also used in the synthesis of a large number of industrial organic compounds. Relatively small quantities of this acid are used for stainless steel pickling and metal etching, and to make rocket propellants. Most phosphoric acid is used as ammonium phosphate in fertilizer and in the manufacture of superphosphates. Phosphoric acid is also used in rustproofing, electropolishing, engraving, lithographic work, coagulation of rubber latex, as an additive in glass manufacture, and as a catalyst in the manufacture of some pharmaceuticals. Sulfuric acid is used in the fertilizer industry for the production of superphosphates and ammonium sulfate.
