摘要
高温示踪剂h30 +和OH−的扩散系数是水热条件下扩散控制反应动力学和质量传递过程建模的重要参数,这些示踪剂扩散系数通过能思-爱因斯坦关系与无限稀释极限下的离子电导率直接相关。h30 +和OH−在水中的极限电导率是由两种不同的离子运动机制控制的:(i)大块离子扩散和(ii)质子跳跃,也被称为“Grotthuss”机制和/或“原生转移”。这项工作报告了对室温以上测量的水溶液HCl, KOH和NaOH的极限电导率数据(Λ°)的关键评估。最初评估的数据集包括温度从273.15 K到873.15 K,水密度从1000 kg m - 3到270 kg m - 3,并减少到最终的严格评估数据集,温度在273.15到678.15 K之间,密度在346到1006 kg m - 3之间。结果被用来推导由于h30 +和OH -的原生转移引起的过量电导率的值,λE°,使用先前报道的水溶液KCl的相关性。推导了Λ°(HCl)、Λ°(KOH)、Λ°(NaOH)、Λ e°(h30 +)和Λ e°(OH−)水粘度与密度的简单经验相关性。利用Λ e°(OH−)相关性和先前报道的Λ°(NaCl)函数进行的测试表明,NaOH数据可以准确地再现到估计的不确定度范围内。所报道的相关性为更准确地模拟h30 +和OH−到超临界条件下的示踪剂扩散系数提供了一种方法。
Critical Review of Transport Properties of HCl, KOH, and NaOH in High Temperature Water and Correlations for Transport Properties of H3O+ and OH−
High-temperature tracer diffusion coefficients for H3O+ and OH− are important parameters in the modeling of diffusion-controlled reaction kinetics and mass transport processes under hydrothermal conditions, and these tracer diffusion coefficients are directly related to the ionic electrical conductivities in the limit of infinite dilution through the Nernst–Einstein relationship. The limiting conductivity of H3O+ and OH− in water is controlled by two separate mechanisms of ionic movement: (i) the bulk ionic diffusion and (ii) proton hopping, also known as “Grotthuss” mechanism and/or “prototropic transfer.” This work reports a critical assessment of the limiting electrical conductivity data (Λ°) for aqueous HCl, KOH, and NaOH measured above room temperature. The initial assessed dataset included temperatures from 273.15 K up to 873.15 K and water densities from 1000 kg m−3 down to 270 kg m−3 and was reduced down to a final critically evaluated dataset spanning temperatures between 273.15 and 678.15 K and densities between 346 and 1006 kg m−3. The results were used to derive values for the excess conductivity due to prototropic transfer, λE°, of H3O+ and OH− using correlations previously reported for aqueous KCl. Simple empirical correlations of water viscosity and density were derived for Λ°(HCl), Λ°(KOH), Λ°(NaOH), λE°(H3O+), and λE°(OH−). Tests using the λE°(OH−) correlation and a previously reported function for Λ°(NaCl) show that the NaOH data can be accurately reproduced to within the estimated uncertainties. The reported correlations provide a means to model more accurately the tracer diffusion coefficients for H3O+ and OH− to supercritical conditions.
期刊介绍:
The Journal of Physical and Chemical Reference Data (JPCRD) is published by AIP Publishing for the U.S. Department of Commerce National Institute of Standards and Technology (NIST). The journal provides critically evaluated physical and chemical property data, fully documented as to the original sources and the criteria used for evaluation, preferably with uncertainty analysis. Critical reviews may also be included if they document a reference database, review the data situation in a field, review reference-quality measurement techniques, or review data evaluation methods.
