摘要
利用从柚子叶、甜菜浆和向日葵花萼中分离出的微凝胶和果胶物质馏分研究了镉离子的吸附机理。评估了果胶多糖的吸附能力、吸附剂对吸附剂的亲和力及其结合强度。研究发现，吸附过程符合 Langmuir 方程。评估了吸附过程在 298.15 至 318.15 K 温度下的热力学参数。发现吸附过程具有放热混合特性。
Thermodynamics of Sorption Processes in Sorbents Based on Pectic Polysaccharides
The sorption mechanism of cadmium ions is studied using isolated fractions of microgel and pectic substances from pomelo albedo, beet pulp, and sunflower calathides. The sorption capacity of pectic polysaccharides, degree of sorbent affinity for the sorbate, and their binding strength are evaluated. The sorption process is found to obey the Langmuir equation. The thermodynamic parameters of the sorption processes at temperatures from 298.15 to 318.15 K are evaluated. The sorption process is found to have an exothermic mixed character.
