CHITOSAN-BASED ORGANOBENTONITES FOR THE SORPTION OF TRANSITION METAL IONS APIS MELLIFERA AND THEIR APPLICATION

The study investigates the processes of metal ion sorption on organobentonites (DB+CH (2), VB+CH (3), PBMB+CH (5)) and organovermiculite (KV+CH (6)), obtained on the basis of Apis Mellifera chitosan from vermiculite clays of Tebinbulak (KV), Dekhkanabad (DB), Navoi (VB), and Navbahor (PBMB, PBG, PBG), located in various regions of the Republic of Uzbekistan. The research examined the dependence of metal sorption on the pH of the medium, the type of organovermiculite, and the type of organosorbent. The processes of sorption and desorption of transition metal ions were studied in detail. The dependence of the static exchange capacity of organosorbents on the pH of the medium was analyzed. The regeneration cycle of the sorbent was found to be of significant importance for the practical application of organosorbents.
