Abstract
The solubility of hydrogen peroxide was measured in aqueous salt solutions containing ammonium sulfate, ammonium nitrate, ammonium chloride, and sodium nitrate. Effective Henry's law constants are reported for these salts at 292 K for concentrations up to 10 M. Salts containing ammonium ions were found to increase the solubility of hydrogen peroxide by up to a factor of two compared to pure water. The data are consistent with a reversible chemical reaction between ammonium ions and hydrogen peroxide. Implications for the aerosol mass loadings of hydrogen peroxide in atmospheric particulate matter and their associated health effects are discussed.
