Diffusion coefficients of sulfur dioxide in hydrogen, helium, and nitrogen were determined by reversed-flow gas chromatography. Experiments were performed at temperatures ranging from 323.3 to 573.3 K and reduced at 101.3 kPa. The precision of the method is 96.6%, while its accuracy is 95.5%. Comparison with values predicted by Fuller–Schettler–Giddings and Huang equations indicates small deviations: the Chen–Otmer equation is successful only for the SO₂–N₂ system. The temperature exponents of SO₂ diffusion are as follows: 1.77, 1.71, and 1.75 in H₂, He, and N₂, respectively. Comparisons with available experimental values for the SO₂–H₂ and SO₂–N₂ systems showed small average deviations: 5.7 and 1.3%, respectively.

反流逆向气相色谱法测定氢气、氦气和氮气中的二氧化硫扩散系数

二氧化硫在氢气、氦气和氮气中的扩散系数通过逆流气相色谱法测定。实验在 323.3 至 573.3 K 的温度范围内进行，并在 101.3 kPa 时降低。该方法的精密度为96.6%，准确度为95.5%。与 Fuller-Schettler-Giddings 和 Huang 方程预测的值进行比较表明偏差很小：Chen-Otmer 方程仅适用于 SO ₂ -N ₂系统。_{SO 2}扩散的温度指数如下：在H ₂、He 和N ₂中分别为1.77、1.71 和1.75。_{与 SO 2} –H ₂和 SO ₂的可用实验值的比较–N ₂系统显示出小的平均偏差：分别为 5.7% 和 1.3%。
