description: The subject of the graduate qualification work is âStudy of the sorption properties of coconut fiber and products of its modification for wastewater treatmentâ. In this research, it is proposed to modify coconut fibers with chemical reagents and the natural compound juglone in order to obtain a highly efficient sorption material. The research set the following goals: Study of the physicochemical properties of the sorbent from coconut fiber. Selection of the heavy metal sorption mode using biosorption materials. Carrying out the modification of coconut fiber with chemical reagents (acids and alkalis) of different concentrations. Modification of coconut fiber with natural component juglone. Evaluation of the efficiency of purification of model solutions with newly obtained sorption materials. The work was carried out on the basis of the Higher School of Biotechnology and Food Production, where the main results of the study were obtained. Studies of the microstructure of the surface of sorption materials were carried out on the basis of the Physicotechnical Institute. A. F. Ioffe. In the course of the work, the effectiveness of coconut fiber as a sorption material was proved, modification with the help of chemical and natural reagents made it possible to obtain a highly effective sorbent in relation to heavy metal ions. With the help of microstructural studies and IR spectroscopy, it was possible to suggest the mechanism of sorption processes. The results of the work can be used as an additional stage of wastewater treatment from heavy metal ions in a complex of treatment facilities or for local treatment.
