Abstract

The sorption mechanism of Cd²⁺ and Pb²⁺ by edible fibers, namely isolated highly purified fractions of pectinic polysaccharides of pomelo albedo, beet pulp, and sunflower calathides, was studied. The Lagergren and Ho-McKay equations were used to evaluate the contribution of a chemical reaction to the sorption process. A relationship was found between the sorption capacity of pectinic polysaccharides and the concentration of free galacturonic acids.

基于果胶多糖的吸附剂的吸附过程机理

研究了食用纤维对 Cd2+ 和 Pb2+ 的吸附机理，即从柚子白皮、甜菜浆和向日葵花萼中分离出的高纯度果胶多糖馏分。拉格伦方程和霍-麦克凯方程被用来评估化学反应对吸附过程的贡献。研究发现，果胶多糖的吸附能力与游离半乳糖醛酸的浓度之间存在一定的关系。
