Abstract

Deliquescence relative humidity (DRH) and efflorescence relative humidity (ERH), the two parameters that regulate phase state and hygroscopicity of substances, play important roles in atmospheric science and many other fields. A large number of experimental studies have measured the DRH and ERH values of compounds with atmospheric relevance, but these values have not yet been summarized in a comprehensive manner. In this work, we develop for the first-of-its-kind a comprehensive database which compiles the DRH and ERH values of 110 compounds (68 inorganics and 42 organics) measured in previous studies, provide the preferred DRH and ERH values at 298 K for these compounds, and discuss the effects of a few key factors (e.g., temperature and particle size) on the measured DRH and ERH values. In addition, we outline future work that will broaden the scope of this database and enhance its accessibility.

摘要

潮解相对湿度（DRH）和风化相对湿度（ERH）是调节物质相态和吸湿性的两个参数，在大气科学及许多其他领域中发挥着重要作用。大量实验研究已测量了与大气相关化合物的DRH和ERH值，但这些值尚未得到全面总结。在本研究中，我们首次开发了一个综合数据库，该数据库汇编了先前研究中测量的110种化合物（68种无机物和42种有机物）的DRH和ERH值，给出了这些化合物在298K时的首选DRH和ERH值，并讨论了一些关键因素（如温度和粒径）对测量的DRH和ERH值的影响。此外，我们概述了未来的工作，这些工作将扩大该数据库的范围并提高其可访问性。
