| 英文摘要 | Methanesulfonate, formed in atmospheric oxidation of dimethyl sulfide, is abundant in marine aerosols; however, its hygroscopic properties have not been well understood. In this work, two complementary techniques (a vapor sorption analyzer and a humidity tandem differential mobility analyzer) were employed to investigate hygroscopic properties of CH3SO3Na, CH3SO3K and (CH3SO3)(2)Ca at different relative humidities (RH). The deliquescence relative humidities were measured to be 70-71% for CH3SO3Na at 15-35 degrees C, displaying no dependence on temperature. The mass changes at 90% RH, relative to that at <1% RH, were measured to be 4.002 +/- 0.053 for CH3SO3Na, 3.479 +/- 0.031 for CH3SO3K, and 3.663 +/- 0.019 for (CH3SO3)(2)Ca at 25 degrees C. CH3SO3Na and CH3SO3K aerosols started to grow at >70% RH, while continuous growth since very low RH (<40%) was observed for (CH3SO3)(2)Ca aerosols. At room temperature, hygroscopic growth factors at 90% RH were measured to be 1.48 +/- 0.02, 1.53 +/- 0.04 and 1.65 +/- 0.02 for CH3SO3Na, CH3SO3K and (CH3SO3)(2)Ca aerosols, respectively. |
