Annotatsiya

This systematic review analyzes the synthesis, characterization, and adsorption efficiency of composite sorbents formed by combining the mineral base kaolin (kaolinite) with the biopolymer chitosan. The review is based on scientific articles published in the Scopus, Web of Science, and ScienceDirect databases between 2020 and 2025. The studies reviewed show that the mechanical and structural stability of kaolin combines synergistically with the high adsorption activity provided by the amino and hydroxyl groups of chitosan. The maximum adsorption capacity was reported to reach 5.5 to 261.7 mg/g for heavy metals and up to 434.8 mg/g for dyes. The adsorption process mainly follows the Langmuir isotherm and pseudo-second-order kinetics; the main mechanisms are coordination (complex formation), electrostatic attraction, and ion exchange. The review identifies research gaps in the field and outlines future directions.
