摘要：

An automated apparatus based on the Ben-Naim-Baer and Tominaga et al. designs [A. Ben-Naim, S. Baer, Trans. Faraday Soc. 59 (1963) 2735-2738; T. Tominaga, R. Battino, H.K. Gorowara, R.D. Dixon, J. Chem. Eng. Data 31 (1986) 175-180] has been implemented for measurements of gas solubilities in liquids under atmospheric pressure and room temperatures. The uncertainty in the measurement of gas solubilities was estimated from the uncertainties in the directly measured quantities using the error propagation law. The accuracy of the experimental method was checked by measuring the solubility of carbon dioxide and nitrous oxide in water in the range T= (290 to 303) K, being found to be 0.6%. A precision of the same order of magnitude was achieved. (c) 2007 Elsevier Ltd. All rights reserved.
