二氧化碳-水系统具有重要的科学和技术意义。因此，人们对它进行了频繁的研究。关于二氧化碳在水中的溶解度的文献很多，而且是跨学科的。进行了一次详尽的调查，发现了大约100项实验研究，发现在压力低于1 Mpa时，报道了平衡数据。基于亨利定律的模型被用来关联低压数据(那些高达1 Mpa的数据)。建立了亨利常数(以摩尔分数表示)的下列关联式：n(H21/Mpa)=-6.8346+1.2817×10(4)/T-3.7668×10(6)/T2+2.997×10(8)/T3该关联式适用于273K(0<；t<；160度-C)，其中T为K。
The system carbon dioxide-water is of great scientific and technological importance. Thus, it has been studied often. The literature for the solubility of carbon dioxide in water is vast and interdisciplinary. An exhaustive survey was conducted and approximately 100 experimental investigations were found that reported equilibrium data at pressures below 1 MPa.A model based on Henry's law was used to correlate the low pressure data (those up to 1 MPa). The following correlation of the Henry's constants (expressed on a mole fraction basis) was developed ln(H21/MPa) = -6.8346 + 1.2817 x 10(4)/T -3.7668 x 10(6)/T2 + 2.997 x 10(8)/T3 The correlation is valid for 273 < T < 433 K (0 < t < 160-degrees-C) where T is in K. Any experimental data that deviated significantly from this model were duly noted.
