摘要

摘要在平衡条件下，研究了三萜皂苷在不同品牌活性碳上的吸附情况。确定了苷的表面活性对曲线走向的影响。吸附等温线的评估采用了一种正式的方法，该方法基于选择尽可能接近地描述所得依赖关系的吸附方程（Langmuir、Freundlich、BET、Redlich-Peterson）。利用 Langmuir 方程坐标中的吸附曲线计算给定过程的热力学特征（吸附能、焓和熵）。

Sorption of Triterpene Glycoside on Different Brands of Active Carbon

Abstract

The sorption of triterpene saponins is studied on different brands of active carbon under equilibrium conditions. The effect the surface activity of glycosides has on the course of the curves is established. Sorption isotherms are assessed using a formal approach based on selecting the sorption equations (Langmuir, Freundlich, BET, Redlich–Peterson) that describe the obtained dependences as closely as possible. Thermodynamic characteristics of the given process (energy of sorption, enthalpy, and entropy) are calculated using sorption curves in the coordinates of the Langmuir equation.
