摘要
以文献发表的67组实验数据依据,研究了用两个经验公式计算二组分全浓度范围内液—固吸附的表面过剩值。依据两个经验方程,用微机对这些实验数据进行拟合,求出对应于每个吸附体系中经验方程的一系列参数值和非线性相关系数r。由对这些体系中r值大小的统计结果表明,在其规定范围内,用这两个经验方程计算表面过剩值是满意的。
Based on 67 sets experimental data about the adsorption from binary liquid mixtures with various kinds of adsorbates and adsorbents published in literatures, two empirical equations which are used to calculate the surface excess on solid surface from binary liquid mixtures are presented.The parameter values involved in the equations and the correlation coefficients, r, of each system were calculated from curve analogue of the corresponding experimental data with computer by the two equations. From the statistics results for r on the 67 systems, it is shown that the two equations are satisfactory for evaluating surface excess uader a given condition.
