The aim of the study was to employ BET, GAB, and Peleg models for mathematical description of sorptive properties of market powder shampoos of natural origin. Two commercial powder shampoos of plant origin (A) and (B) were used as study materials. The sorption isotherm of powder shampoo was much higher in the standard reference system in comparison to shampoo. The B shampoo had a higher monolayer capacity than product A. The examined process in both cases was physical in nature. The most useful for isothermal description turned out to be the theoretical BET equation and empirical Peleg model. They were characterized by high accuracy. Natural powder shampoos differed significantly in terms of physical parameters of particles and sorptive properties, which may suggest their different functional properties.
该研究的目的是采用BET、GAB和佩莱格模型对天然来源的市售粉末状洗发水的吸附特性进行数学描述。两种植物源商业粉末状洗发水（A）和（B）用作研究材料。与洗发水相比，粉末状洗发水在标准参考体系中的吸附等温线要高得多。B洗发水的单层容量高于产品A。两种情况下所研究的过程本质上都是物理过程。结果表明，对等温线描述最有用的是理论BET方程和经验佩莱格模型。它们具有很高的准确性。天然粉末状洗发水在颗粒物理参数和吸附特性方面存在显著差异，这可能表明它们具有不同的功能特性。
