摘要

The deliquescence relative humidities (DRH) as a function of temperature have been determined for several salts of atmospheric importance using humidity controlled thermogravimetric analysis (HTGA): sodium hydrogen oxalate monohydrate (NaHC2O4H2O), sodium oxalate (Na2C2O4), sodium ammonium sulfate dihydrate (NaNH4SO4.2H(2)O, lecontite), sodium hydrogen malonate monohydrate (NaHC3H2O4.H2O), sodium malonate monohydrate (Na2C3H2O4.H2O), and ammonium hydrogen malonate (NH4HC3H2O4). The temperature dependent onset DRH values (where a dry mixture begins to take up water) were also determined for mixtures of ammonium sulfate with malonic acid, and ammonium sulfate with sodium oxalates and sodium malonates, respectively. We demonstrate that the onset DRH is independent of the ratio of solids in the mixture. In general, onset DRH values were always lower than the pure component DRH values.
